The Western Desert Force (WDF) was a British Army formation active in Egypt during the Western Desert Campaign of the Second World War.
General Sir Richard Nugent O'Connor, was a senior British Army officer who fought in both the First and Second World Wars, and commanded the Western Desert Force in the early years of the Second World War. He was the field commander for Operation Compass, in which his forces destroyed a much larger Italian army – a victory which nearly drove the Axis from Africa, and in turn, led Adolf Hitler to send the Afrika Korps under Erwin Rommel to try to reverse the situation. O'Connor was captured by a German reconnaissance patrol during the night of 7 April 1941 and spent over two years in an Italian prisoner of war camp. He eventually escaped after the fall of Mussolini in the autumn of 1943. In 1944 he commanded VIII Corps in the Battle of Normandy and later during Operation Market Garden. In 1945 he was General Officer in Command of the Eastern Command in India and then, in the closing days of British rule in the subcontinent, he headed Northern Command. His final job in the army was Adjutant-General to the Forces in London, in charge of the British Army's administration, personnel and organisation.
Operation Compass was the first large British military operation of the Western Desert Campaign (1940–1943) during the Second World War. British, Empire and Commonwealth forces attacked Italian forces of the 10th Army in western Egypt and Cyrenaica, the eastern province of Libya, from December 1940 to February 1941.
I Corps was an army corps in existence as an active formation in the British Army for most of the 80 years from its creation in the First World War until the end of the Cold War, longer than any other corps. It had a short-lived precursor during the Waterloo Campaign.
The 15th Army Group was an Army Group in World War II, composed of the British Eighth and the U.S. Fifth Armies, which apart from troops from the British Empire and U.S.A., also had whole units from other allied countries/regions; like two of their Corps, one Division and multiple separate brigades, besides supporting and being supported by the local Italian partisans. It operated in the Italian Campaign between 1943–45.
The 2nd New Zealand Division, initially the New Zealand Division, was an infantry division of the New Zealand Military Forces during the Second World War. The division was commanded for most of its existence by Lieutenant-General Bernard C. Freyberg. It fought in Greece, Crete, the Western Desert and Italy. In the Western Desert Campaign, the division played a prominent role in the defeat of German and Italian forces in the Second Battle of El Alamein and the British Eighth Army's advance to Tunisia.
XXX Corps was a corps of the British Army during the Second World War. The corps was formed in the Western Desert in September 1941. It provided extensive service in the North African Campaign and many of its units were in action at the Second Battle of El Alamein in late 1942. It then took part in the Tunisia Campaign and formed the left flank during the Allied invasion of Sicily in 1943.
VIII Corps was a British Army corps formation that existed during the First and Second World Wars. In the latter, it took part in the Normandy Campaign in 1944, where it was involved in Operation Epsom and Operation Goodwood. It would later play a supporting role in Operation Market Garden and finish the war by advancing from the Rhine to the Baltic Sea.
IX Corps was a corps-sized formation of the British Army that existed during the First and the Second World Wars.
The Western Desert campaign took place in the deserts of Egypt and Libya and was the main theatre in the North African campaign of the Second World War. Military operations began in June 1940 with the Italian declaration of war and the Italian invasion of Egypt from Libya in September. Operation Compass, a five-day raid by the British in December 1940, was so successful that it led to the destruction of the Italian 10th Army over the following two months. Benito Mussolini sought help from Adolf Hitler, who sent a small German force to Tripoli under Directive 22. The Afrika Korps was formally under Italian command, as Italy was the main Axis power in the Mediterranean and North Africa.
The 21st Panzer Division was a German armoured division best known for its role in the battles of the North African Campaign from 1941–1943 during World War II when it was one of the two armoured divisions making up the Deutsches Afrikakorps (DAK).
The 5th Indian Infantry Division was an infantry division of the Indian Army during World War II that fought in several theatres of war and was nicknamed the "Ball of Fire". It was one of the few Allied divisions to fight against three different armies - the Italian, German and Japanese armies.
The 8th Mountain Division was raised as the 8th Indian Infantry division of the British Indian Army. It is now part of the Indian Army and specialises in mountain warfare.
The 18th Infantry Brigade was an infantry brigade of the British Army that saw active service during the First and the Second World Wars.
X Corps was a corps of the British Army that served in the First World War on the Western Front before being disbanded in 1919. The corps was re-formed in 1942 during the Second World War and saw service in the North African Campaign and the Italian Campaign where it came under command of the US Fifth Army and the British Eighth Army.
Lieutenant General Sir Dudley Russell KBE, CB, DSO, MC was a senior officer of both the British Army and the British Indian Army, and served during World War I and World War II, where he commanded the 8th Indian Infantry Division during the Italian Campaign from late 1943 until the end of the war in 1945.
V Corps was an army corps of the British Army that saw service in both the First and the Second World Wars. It was first organised in February 1915 and fought through the First World War on the Western front. It was recreated in June 1940, during the Second World War and was substantially reorganised in 1942 for participation in Operation Torch. It fought through the Tunisia Campaign and later the Italian Campaign.
The Italian invasion of Egypt was an offensive in the Second World War, against British, Commonwealth and Free French forces in the Kingdom of Egypt. The invasion by the Italian 10th Army ended border skirmishing on the frontier and began the Western Desert Campaign (1940–1943) proper. The Italian strategy was to advance from Libya along the Egyptian coast to seize the Suez Canal. After numerous delays, the scope of the offensive was reduced to an advance as far as Sidi Barrani and the engagement of any British forces in the area.
At the start of 1939, the British Army was, as it traditionally always had been, a small volunteer professional army. At the beginning of the Second World War on 1 September 1939, the British Army was small in comparison with those of its enemies, as it had been at the beginning of the First World War in 1914. It also quickly became evident that the initial structure and manpower of the British Army was woefully unprepared and ill-equipped for a war with multiple enemies on multiple fronts. During the early war years, mainly from 1940 to 1942, the British Army suffered defeat in almost every theatre of war in which it was deployed. But, from late 1942 onwards, starting with the Second Battle of El Alamein, the British Army's fortunes changed and it rarely suffered another defeat.
The Eighth Army was a field army of the British Army during the Second World War. It was initially formed as the Western Army on 10 September 1941, in Egypt, before being renamed the Army of the Nile, and finally the Eighth Army on 26 September. It was created to better control the growing Allied forces based in Egypt and to direct their efforts to lift the siege of Tobruk via Operation Crusader.
