Location of Diego-Suarez Bay

The Battle of Madagascar was the British campaign to capture the Vichy French-controlled island Madagascar during World War II. The seizure of the island by the British was to deny Madagascar's ports to the Imperial Japanese Navy and to prevent the loss or impairment of the Allied shipping line. It began with Operation Ironclad, the seizure of the port of Diego-Suarez (now Antsiranana) near the northern tip of the island, on 5 May 1942. [1]

British Empire States and dominions ruled by the United Kingdom

The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23% of the world population at the time, and by 1920, it covered 35,500,000 km2 (13,700,000 sq mi), 24% of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.

Vichy France officially the French State, was France during the regime of Marshal Philippe Pétain, during World War II

Vichy France is the common name of the French State headed by Marshal Philippe Pétain during World War II. Evacuated from Paris to Vichy in the unoccupied "Free Zone" in the southern part of metropolitan France which included French Algeria, it remained responsible for the civil administration of France as well as the French colonial empire.

French Madagascar former French colony in Southeast Africa

The Colony of Madagascar and Dependencies was a French colony off the coast of Southeast Africa between 1897 and 1958.

A subsequent campaign to secure the entire island, Operation Stream Line Jane, was opened on 10 September. The Allies broke into the interior linking up with forces on the coast and secured the island by the end of October. Fighting ceased and an armistice was granted on 6 November. [5] This was the first large scale operation by the Allies of World War II combining sea, land and air forces. [6]

Combined arms military operations and doctrine utilizing different branches in combination

Combined arms is an approach to warfare which seeks to integrate different combat arms of a military to achieve mutually complementary effects. According to strategist William S. Lind, combined arms can be distinguished from the concept of "supporting arms" as follows:

Combined arms hits the enemy with two or more arms simultaneously in such a manner that the actions he must take to defend himself from one make him more vulnerable to another. In contrast, supporting arms is hitting the enemy with two or more arms in sequence, or if simultaneously, then in such combination that the actions the enemy must take to defend himself from one also defends himself from the other(s).



Diego-Suarez is a large bay with a fine harbour near the northern tip of the island of Madagascar and has an opening to the east through a narrow channel called Oronjia Pass. The naval base of Diego-Suarez lies on a peninsula between two of the four small bays enclosed within Diego-Suarez Bay. Diego-Suarez Bay cuts deeply into the northern tip of Madagascar (Cape Amber), almost severing it from the rest of the island. [7] :133 In the 1880s, the bay was coveted by France, which claimed it as a coaling station for steamships travelling to French possessions farther east. The colonization was formalized after the first Franco-Hova War when Queen Ranavalona III signed a treaty on 17 December 1885 giving France a protectorate over the bay and surrounding territory, as well as the islands of Nosy Be and St. Marie de Madagascar. The colony's administration was subsumed into that of French Madagascar in 1897. [8]

Antsiranana Bay Natural bay along the northeast coast of Madagascar

Antsiranana Bay is a natural bay that stretches close to 20 kilometres (12 mi) north to south along the northeast coast of Madagascar. The waters average a depth of more than 20 metres (66 ft), and the main channel can be as deep as 50 metres (160 ft). The bay, protected by a narrow inlet that provides shelter from strong Indian Ocean winds, is believed to be the result of a submerging coastline or a drowned river valley that formed many peninsulas around the bay.

Franco-Hova Wars

The Franco-Hova Wars or Franco-Malagasy Wars comprised two French military interventions in Madagascar between 1883 and 1896 that overthrew the ruling monarchy of the Merina Kingdom, and resulted in Madagascar becoming a French colony. Hova refers to a class within the Merina social structure.

A protectorate, in its inception adopted by modern international law, is a dependent territory that has been granted local autonomy and some independence while still retaining the suzerainty of a greater sovereign state. In exchange for this, the protectorate usually accepts specified obligations, which may vary greatly, depending on the real nature of their relationship. Therefore, a protectorate remains an autonomous part of a sovereign state. They are different from colonies as they have local rulers and people ruling over the territory and experience rare cases of immigration of settlers from the country it has suzerainty of. However, a state which remains under the protection of another state but still retains independence is known as a protected state and is different from protectorates.

In 1941, Diego-Suarez town, the bay and the channel were well protected by naval shore batteries. [7] :133

Coastal artillery Military service branch equipped with artillery in defense of territory against attack from the sea

Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications.


Following the Japanese conquest of Southeast Asia east of Burma by the end of February 1942, submarines of the Imperial Japanese Navy were moving freely throughout the north and eastern expanses of the Indian Ocean. In March 1942, Japanese aircraft carriers conducted the Indian Ocean raid upon shipping in the Bay of Bengal and bases in Colombo and Trincomalee in Ceylon (now Sri Lanka). This raid drove the British Eastern Fleet out of the area and they were forced to relocate to a new base at Kilindini, near Mombasa, in Kenya.

Dutch East Indies campaign conflict

The Dutch East Indies Campaign of 1941–1942 was the conquest of the Dutch East Indies by forces from the Empire of Japan in the early days of the Pacific Campaign of World War II. Forces from the Allies attempted unsuccessfully to defend the islands. The East Indies were targeted by the Japanese for their rich oil resources which would become a vital asset during the war. The campaign and subsequent three and a half year Japanese occupation was also a major factor in the end of Dutch colonial rule in the region.

Southeast Asia Subregion of Asia

Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China and Japan, east of India, west of Papua New Guinea, and north of Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean. The region is the only part of Asia that lies partly within the Southern Hemisphere, although the majority of it is in the Northern Hemisphere. In contemporary definition, Southeast Asia consists of two geographic regions:

  1. Mainland Southeast Asia, also known historically as Indochina, comprising parts of Northeast India, Vietnam, Laos, Cambodia, Thailand, Myanmar and West Malaysia.
  2. Maritime Southeast Asia, also known historically as Nusantara, the East Indies and Malay Archipelago, comprises the Andaman and Nicobar Islands of India, Indonesia, East Malaysia, Singapore, the Philippines, East Timor, Brunei, Christmas Island, and the Cocos (Keeling) Islands.
Submarine Watercraft capable of independent operation underwater

A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub.

The move made the British fleet more vulnerable to attack. The possibility of Japanese naval forces using forward bases in Madagascar had to be addressed. The potential use of these facilities particularly threatened Allied merchant shipping, the supply route to the British Eighth Army and also the Eastern Fleet.

Allies of World War II Grouping of the victorious countries of World War II

The Allies of World War II, called the "United Nations" from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War (1939–1945). The Allies promoted the alliance as a means to control German, Japanese and Italian aggression.

Japanese submarines had the longest range of any Axis forces' subs at the time — more than 10,000 miles (16,000 km) in some cases,[ citation needed ] but being challenged by the United States Navy's then-relatively new Gato-class fleet submarines' 11,000 nautical mile s (20,000 km) top range figures. If the Imperial Japanese Navy's submarines were able to utilise bases on Madagascar, Allied lines of communication would be affected across a region stretching from the Pacific and Australia, to the Middle East and as far as the South Atlantic.

On 17 December 1941, Vice Admiral Fricke, Chief of Staff of Germany's Maritime Warfare Command (Seekriegsleitung), met Vice Admiral Naokuni Nomura, the Japanese Naval Attaché, in Berlin to discuss the delimitation of respective operational areas between the German Kriegsmarine and Imperial Japanese Navy forces. At another meeting on 27 March 1942, Fricke stressed the importance of the Indian Ocean to the Axis powers and expressed the desire that the Japanese begin operations against the northern Indian Ocean sea routes. Fricke further emphasized that Ceylon, the Seychelles, and Madagascar should have a higher priority for the Axis navies than operations against Australia. [7] :116 By 8 April, the Japanese announced to Fricke that they intended to commit four or five submarines and two auxiliary cruisers for operations in the western Indian Ocean between Aden and the Cape of Good Hope, but they refused to disclose their plans for operations against Madagascar and Ceylon, only reiterating their commitment to operations in the area. [7] :117


The Allies had heard the rumours of Japanese plans for the Indian Ocean and on 27 November 1941, the British Chiefs of Staff discussed the possibility that the Vichy government might cede the whole of Madagascar to Japan, or alternatively permit the Japanese Navy to establish bases on the island. British naval advisors urged the occupation of the island as a precautionary measure. [7] :131 On 16 December, General Charles de Gaulle, leader of the Free French in London, sent a letter to the British Prime Minister, Winston Churchill, in which he also urged a Free French operation against Madagascar. [9] :223 Churchill recognised the risk of a Japanese-controlled Madagascar to Indian Ocean shipping, particularly to the important sea route to India and Ceylon, and considered the port of Diego-Suarez as the strategic key to Japanese influence in the Indian Ocean. However, he also made it clear to planners that he did not feel Britain had the resources to mount such an operation and, following experience in the Battle of Dakar in September 1940, did not want a joint operation launched by British and Free French forces to secure the island. [9] :223

By 12 March 1942, Churchill had been convinced of the importance of such an operation and the decision was reached that the planning of the invasion of Madagascar would begin in earnest. It was agreed that the Free French would be explicitly excluded from the operation. As a preliminary battle outline, Churchill gave the following guidelines to the planners [9] :225 and the operation was designated Operation Bonus: [9] :225

On 14 March, Force 121 was constituted under the command of Major-General Robert Sturges of the Royal Marines with Rear-Admiral Edward Syfret being placed in command of naval Force H and the supporting sea force. [7] :132

Allied preparations

Map of the assault

Force 121 left the Clyde in Scotland on 23 March and joined with South African-born Syfret's ships at Freetown in Sierra Leone, proceeding from there in two convoys to their assembly point at Durban on the South African east coast. Here they were joined by the 13th Brigade Group of the 5th Division – General Sturges' force consisting of three infantry brigades, while Syfret's squadron consisted of the flag battleship HMS Ramillies, the aircraft carriers HMS Illustrious and HMS Indomitable, the cruisers HMS Hermione and HMS Devonshire, eleven destroyers, six minesweepers, six corvettes and auxiliaries. It was a formidable force to bring against the 8,000 men (mostly Malagasy) at Diego-Suarez, but the chiefs of staff were adamant that the operation was to succeed, preferably without any fighting. [7] :132

This was to be the first British amphibious assault since the disastrous landings in the Dardanelles twenty-seven years before. [9] :230

During the assembly in Durban, Field-Marshal Jan Smuts pointed out that the mere seizure of Diego-Suarez would be no guarantee against continuing Japanese aggression and urged that the ports of Majunga and Tamatave be occupied as well. This was evaluated by the chiefs of staff, but it was decided to retain Diego-Suarez as the only objective due to the lack of manpower. [7] :132 Churchill remarked that the only way to permanently secure Madagascar was by means of a strong fleet and adequate air support operating from Ceylon and sent General Archibald Wavell (India Command) a note stating that as soon as the initial objectives had been met, all responsibility for safeguarding Madagascar would be passed on to Wavell. He added that when the commandos were withdrawn, garrison duties would be performed by two African brigades and one brigade from the Belgian Congo or west coast of Africa. [9] :231

In March and April, the South African Air Force (SAAF) had conducted reconnaissance flights over Diego-Suarez and No. 32, 36 and 37 Coastal Flights were withdrawn from maritime patrol operations and sent to Lindi on the Indian Ocean coast of Tanganyika, with an additional eleven Bristol Beauforts and six Martin Marylands to provide close air support during the planned operations. [7] :133


Allied commanders decided to launch an amphibious assault on Madagascar. The task was Operation Ironclad and executed by Force 121. It would include allied naval, land and air forces and be commanded by Major-General Robert Sturges of the Royal Marines. The British Army landing force included the 29th Independent Infantry Brigade Group, No 5 (Army) Commando, and two brigades of the 5th Infantry Division, the latter en route to India with the remainder of their division. The Allied naval contingent consisted of over 50 vessels, drawn from Force H, the British Home Fleet and the British Eastern Fleet, commanded by Syfret. The fleet included the aircraft carrier Illustrious, her sister ship Indomitable and the ageing battleship Ramillies to cover the landings.

Landings (Operation Ironclad)

Following many reconnaissance missions by the SAAF, the first wave of the British 29th Infantry Brigade and No. 5 Commando landed in assault craft on 5 May 1942. Follow-up waves were by two brigades of the 5th Infantry Division and Royal Marines. All were carried ashore by landing craft to Courrier Bay and Ambararata Bay, just west of the major port of Diego-Suarez, at the northern tip of Madagascar. A diversionary attack was staged to the east. Air cover was provided mainly by Fairey Albacore and Fairey Swordfish torpedo bombers which attacked Vichy shipping. They were supported by Grumman Martlets fighters from the Fleet Air Arm. A small number of SAAF planes assisted.

The defending Vichy forces, led by Governor General Armand Léon Annet, included about 8,000 troops, of whom about 6,000 were Malagasy tirailleurs (colonial infantry). A large proportion of the rest were Senegalese. Between 1,500 and 3,000 Vichy troops were concentrated around Diego-Suarez. [1] However, naval and air defences were relatively light and/or obsolete: eight coastal batteries, two armed merchant cruisers, two sloops, five submarines, 17 Morane-Saulnier 406 fighters and 10 Potez 63 bombers.

The beach landings met with virtually no resistance and these troops seized Vichy coastal batteries and barracks. The Courier Bay force, the 17th Infantry Brigade, after toiling through mangrove swamp and thick bush took the town of Diego-Suarez taking a hundred prisoners. The Ambararata Bay force, the 29th Independent Brigade, headed towards the French naval base of Antisarane. [1] With assistance from six Valentines and six Tetrarch light tanks of B Special Service Squadron they advanced 21 miles overcoming light resistance with bayonet charges. [10] Antisarane itself was heavily defended with trenches, two redoubts, pillboxes, and flanked on both sides by impenetrable swamps. [11]

On the morning of 6 May 1942 a frontal assault on the defences failed with the loss of three Valentines and two Tetrarchs. [10] Another assault by the South Lancashires worked their way around the defences but the swamps and bad terrain meant they were broken up into groups. Nevertheless, they swung behind the Vichy line and caused chaos. Fire was poured on the Vichy defences from behind and the radio station and a barracks were seized. [11] In all 200 prisoners were taken, but the South Lancs had to withdraw as communication with the main force was nonexistent after the radio set failed. With the French defence highly effective, the deadlock was broken when the old destroyer HMS Anthony dashed straight past the harbour defences of Antisarane and landed fifty Royal Marines from Ramillies amidst the Vichy rear area. [11] The marines created "disturbance in the town out of all proportion to their numbers" taking the French artillery command post along with its barracks and the naval depot. At the same time the troops of the 17th Infantry Brigade had broken through the defences and were soon marching in the town. The Vichy defence was broken and Antisarane surrendered that evening, although substantial Vichy forces withdrew to the south. [12]

The Japanese submarines I-10, I-16, and I-20 arrived three weeks later on 29 May 1942. I-10's reconnaissance plane spotted HMS Ramillies at anchor in Diego-Suarez harbour, but the plane was spotted and Ramillies changed her berth. I-20 and I-16 launched two midget submarines, one of which managed to enter the harbour and fired two torpedoes while under depth charge attack from two corvettes. One torpedo seriously damaged Ramillies, while the second sank the 6,993-ton oil tanker British Loyalty (later refloated). [13] Ramillies was later repaired in Durban and Plymouth.

The crew of one of the midget submarines, Lieutenant Saburo Akieda and Petty Officer Masami Takemoto, beached their craft (M-20b) at Nosy Antalikely and moved inland towards their pick-up point near Cape Amber. They were betrayed when they bought food at the village of Anijabe and both were killed in a firefight with Royal Marines three days later. One marine was killed in the action as well. The second midget submarine was lost at sea and the body of a crewman was found washed ashore a day later. [13]

Hostilities continued at a low level for several months. After 19 May 1942 two brigades of the 5th Infantry Division were transferred to India. On 8 June 1942, the 22nd (East Africa) Brigade Group arrived on Madagascar [14] The 7th South African Motorized Brigade arrived on 24 June 1942. [15] The 27th (North Rhodesia) Infantry Brigade (including forces from East Africa) landed on 8 August. [16]

The operation code-named "Stream Line Jane" (sometimes given as "Streamline Jane") consisted of three separate sub-operations code-named Stream, Line and Jane. Stream and Jane were, respectively, the amphibious landings at Majunga on 10 September and Tamatave on 18 September, while Line was the advance from Majunga to the French capital, Tannanarive, which fell on 23 September. [17] [18]

On 10 September 1942 the 29th Brigade and 22nd Brigade Group made an amphibious landing at Majunga, another port on the west coast of the island. No. 5 Commando spearheaded the landing and faced machine gun fire but despite this they stormed the quayside, took control of the local post office, stormed the governor's residence and raised the Union Jack. [19] Having severed communications with Tannanarive, the allies intended to re-launch the offensive ahead of the rainy season. Progress was slow for the Allied forces. In addition to occasional small-scale clashes with Vichy forces, they also encountered scores of obstacles erected on the main roads by Vichy soldiers. The Allies eventually captured the capital, Tananarive, without much opposition, and then the town of Ambalavao, but the devoutly Vichy Governor Annet escaped. [20]

Eight days later a British force set out to seize Tamatave. Heavy surf interfered with the operation. As HMS Birmingham's launch was heading to shore it was fired at by French shore batteries and promptly turned around. Birmingham then opened her guns up on the shores batteries and within three minutes the French hauled up the white flag. Tamatave fell into British hands. From there the South Lancashires and the Royal Welch Fusiliers set out to the south to link up with forces there. After they reached Tananarive they pressed on towards Moramanga and on 25 September 1942 they linked up with the Kings African Rifles having secured the British lines of communication around the island. At the same time the East African infantry and South African armoured cars set out to find the elusive Governor Annet. [20]

The last major action took place on 18 October , at Andramanalina, a U-shaped valley with the meandering Mangarahara River where an ambush was planned for British forces by Vichy troops. The King African Rifles split into two columns and marched around the 'U' of the valley and met Vichy troops in the rear and then ambushed them. The Vichy troops suffered heavy losses which resulted in 800 of them surrendering. [20] A week later the Kings African rifles then entered Fianarantosa but found Annet gone, this time near Ihosy 100 miles south. The Africans swiftly moved after him, but they received an envoy from Annet asking for terms of surrender. He had had enough and couldn't escape further. An armistice was signed in Ambalavao on 6 November 1942, and Annet surrendered two days later. [21]

The Allies suffered about 500 casualties in the landing at Diego-Suarez, and 30 more killed and 90 wounded in the operations which followed on 10 September 1942.

Julian Jackson, in his biography of de Gaulle [22] , observed that the French had held out longer against the Allies in Madagascar in 1942 than they had against the Germans in France in 1940.

With Madagascar in Allied hands, they established military and naval installations across the island. The island was crucial for the rest of the war. Its deep water ports were vital to control the passageway to India and the Persian corridor, and this was now beyond the grasp of the Axis. [20] This was the first large scale operation of World War II by the allies combining sea, land, and air forces. In the makeshift allied planning of the war's early years, the invasion of Madagascar held a prominent strategic place. [6]

Free French General Paul Legentilhomme was appointed High Commissioner for Madagascar. Like many colonies, Madagascar sought its independence following the war. In 1947, the island experienced the Malagasy Uprising, a costly revolution that was crushed in 1948. It was not until 26 June 1960, about twelve years later, that the Malagasy Republic successfully proclaimed its independence from France.

Campaign service in Madagascar did not qualify for the British and Commonwealth Africa Star. It was instead covered by the 1939–1945 Star. [23]

Light Tank Mk VII Tetrarch 1938 light tank

The Light Tank Mk VII (A17), also known as the Tetrarch, was a British light tank produced by Vickers-Armstrongs in the late 1930s and deployed during the Second World War. The Tetrarch was originally designed as the latest in the line of light tanks built by the company for the British Army. It improved upon its predecessor, the Mk VIB Light Tank, by introducing the extra firepower of a 2-pounder gun. The War Office ordered 70 tanks, an order that eventually increased to 220. Production was delayed by several factors, and as a consequence, only 100 to 177 of the tanks were produced.

Madagascar in World War II

Madagascar, then officially known as French Madagascar, was still a French colony at the outbreak of the Second World War, having been under French administration since 1885.

After the fall of France in 1940, Madagascar became a crucial flashpoint in contention between the Free French movement and Vichy France. The island was also consequential in the Pacific theater of the war as Imperial Japanese naval forces operated unopposed off the island for some time.

HMS <i>Ramillies</i> (07) battleship

HMS Ramillies was one of five Revenge-class super-dreadnought battleships built for the Royal Navy during the First World War. They were developments of the Queen Elizabeth-class battleships, with reductions in size and speed to offset increases in the armour protection whilst retaining the same main battery of eight 15-inch (381 mm) guns. Completed in late 1917, Ramillies saw no combat during the war as both the British and German fleets had adopted a more cautious strategy by this time owing to the increasing threat of naval mines and submarines.
