The Second Battle of the Marne was the last major German offensive on the Western Front during the First World War. The attack failed when an Allied counterattack, supported by several hundreds of tanks, overwhelmed the Germans on their right flank, inflicting severe casualties. The German defeat marked the start of the relentless Allied advance which culminated in the Armistice with Germany about 100 days later.
The German spring offensive, or Kaiserschlacht, also known as the Ludendorff offensive, was a series of German attacks along the Western Front during the First World War, beginning on 21 March 1918. Following American entry into the war in April 1917, the Germans decided that their only remaining chance of victory was to defeat the Allies before the United States could ship soldiers across the Atlantic and fully deploy its resources. The German Army had gained a temporary advantage in numbers as nearly 50 divisions had been freed by the Russian defeat and withdrawal from the war with the Treaty of Brest-Litovsk.
Lord Strathcona's Horse (Royal Canadians) (LdSH[RC]) is a regular armoured regiment of the Canadian Army and is Canada’s only tank regiment. Currently based in Edmonton, Alberta, the regiment is part of 3rd Canadian Division's 1 Canadian Mechanized Brigade Group. Members of the regiment are commonly called Strathconas or Strats as a short form. It was one of the last regiments in the British Empire to be created and raised by a private individual, Donald Alexander Smith, 1st Baron Strathcona and Mount Royal.
Gordon Muriel Flowerdew was an English-born Canadian recipient of the Victoria Cross, the highest and most prestigious award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces, received for his actions at the Battle of Moreuil Wood.
The Hindenburg Line was a German defensive position built during the winter of 1916–1917 on the Western Front in France during the First World War. The line ran from Arras to Laffaux, near Soissons on the Aisne. In 1916, the Battle of Verdun and the Battle of the Somme left the German western armies exhausted and on the Eastern Front, the Brusilov Offensive had inflicted huge losses on the Austro-Hungarian armies and forced the Germans to take over more of the front. The declaration of war by Romania had placed additional strain on the German army and war economy.
The Battle of Amiens, also known as the Third Battle of Picardy, was the opening phase of the Allied offensive which began on 8 August 1918, later known as the Hundred Days Offensive, that ultimately led to the end of the First World War. Allied forces advanced over 11 kilometres (7 mi) on the first day, one of the greatest advances of the war, with Gen Henry Rawlinson's British Fourth Army and Gen Marie Eugène Debeney's French First Army playing the decisive role. The battle is also notable for its effects on both sides' morale and the large number of surrendering German forces. This led Erich Ludendorff to later describe the first day of the battle as "the black day of the German Army". Amiens was one of the first major battles involving armoured warfare.
The Battle of Arras was a British offensive on the Western Front during the First World War. From 9 April to 16 May 1917, British troops attacked German defences near the French city of Arras on the Western Front. The British achieved the longest advance since trench warfare had begun, surpassing the record set by the French Sixth Army on 1 July 1916. The British advance slowed in the next few days and the German defence recovered. The battle became a costly stalemate for both sides and by the end of the battle, the British Third Army and the First Army had suffered about 160,000 casualties and the German 6th Army about 125,000.
The Canadian Expeditionary Force (CEF) was the expeditionary field force of Canada during the First World War. It was formed following Britain’s declaration of war on Germany on 15 August 1914, with an initial strength of one infantry division. The division subsequently fought at Ypres on the Western Front, with a newly raised second division reinforcing the committed units to form the Canadian Corps. The CEF and corps was eventually expanded to four infantry divisions, which were all committed to the fighting in France and Belgium along the Western Front. A fifth division was partially raised in 1917, but was broken up in 1918 and used as reinforcements following heavy casualties.
The Third Battle of the Aisne was a battle of the German spring offensive during World War I that focused on capturing the Chemin des Dames Ridge before the American Expeditionary Forces arrived completely in France. It was one of a series of offensives, known as the Kaiserschlacht, launched by the Germans in the spring and summer of 1918.
The 10th Cavalry Brigade was a Polish military unit in World War II. It was the only fully operational Polish motorized infantry unit during the Invasion of Poland, as Warsaw Armoured Motorized Brigade was not completed by September 1, 1939.
The Battle of the Avre, part of the First Battle of Villers-Bretonneux, constituted the final German attack towards Amiens in World War I. It was the point at which the Germans got the closest to Amiens. It was fought between attacking German troops and defending Australian and British troops. The attack was an attempt to take Amiens, where other aspects of Operation Michael had failed. The Avre marked the beginning of the end for Ludendorf's German spring offensive.
The United States campaigns in World War I began after American entry in the war in early April 1917. The American Expeditionary Force (AEF) served on the Western Front, under General John J. Pershing, and engaged in 13 official military campaigns between 1917 and 1918, for which campaign streamers were designated. The streamer uses the colors of the World War I Victory Medal ribbon which had a red center with a rainbow on each side of the center stripe and a purple edge. The double rainbow symbolizes the dawn of a new era and the calm which follows the storm.
The First Battle of Villers-Bretonneux, took place during Operation Michael, part of the German spring offensive on the Western Front. The offensive began against the British Fifth Army and the Third Army on the Somme and pushed back the British and French reinforcements on the north side of the Somme. The capture of Villers-Bretonneux, close to Amiens, a strategically important road- and rail-junction, would have brought the Germans within artillery-range. In late March, Australian troops were brought south from Belgium as reinforcements to help shore up the line and in early April the Germans launched an attack to capture Villers-Bretonneux. After a determined defence by British and Australian troops, the attackers were close to success until a counter-attack by the 9th Australian Infantry Brigade and by British troops, late in the afternoon of 4 April, restored the line and halted the German advance on Amiens.
The use of horses in World War I marked a transitional period in the evolution of armed conflict. Cavalry units were initially considered essential offensive elements of a military force, but over the course of the war, the vulnerability of horses to modern machine gun, mortar, and artillery fire reduced their utility on the battlefield. This paralleled the development of tanks, which ultimately replaced cavalry in shock tactics. While the perceived value of the horse in war changed dramatically, horses still played a significant role throughout the war.
The Battle of Armentières was fought by German and Franco-British forces in northern France in October 1914, during reciprocal attempts by the armies to envelop the northern flank of their opponent, which has been called the Race to the Sea. Troops of the British Expeditionary Force (BEF) moved north from the Aisne front in early October and then joined in a general advance with French troops further south, pushing German cavalry and Jäger back towards Lille until 19 October. German infantry reinforcements of the 6th Army arrived in the area during October.
Operation Michael was a major German military offensive during the First World War that began the German Spring Offensive on 21 March 1918. It was launched from the Hindenburg Line, in the vicinity of Saint-Quentin, France. Its goal was to break through the Allied (Entente) lines and advance in a north-westerly direction to seize the Channel Ports, which supplied the British Expeditionary Force (BEF), and to drive the BEF into the sea. Two days later General Erich Ludendorff, the chief of the German General Staff, adjusted his plan and pushed for an offensive due west, along the whole of the British front north of the River Somme. This was designed to first separate the French and British Armies before continuing with the original concept of pushing the BEF into the sea. The offensive ended at Villers-Bretonneux, to the east of the Allied communications centre at Amiens, where the Allies managed to halt the German advance; the German Army had suffered many casualties and was unable to maintain supplies to the advancing troops.
The Canadian Cavalry Brigade was raised in December 1914, under its first commanding officer Brigadier-General J.E.B. Seely. It was originally composed of two Canadian and one British regiments and an attached artillery battery. The Canadian units were the Royal Canadian Dragoons, Lord Strathcona's Horse and the Royal Canadian Horse Artillery battery. The British regiment was the 2nd King Edward's Horse. 2KEH was replaced by The Fort Garry Horse in February 1916.
The siege of the Salamanca forts saw an 800-man Imperial French garrison directed by Lieutenant Colonel Duchemin defend three fortified convents in the city of Salamanca against the 48,000-strong Allied army led by Arthur Wellesley, Lord Wellington. During this time, the French commander Marshal Auguste de Marmont led a 40,000-man French army in an unsuccessful attempt to relieve the garrison. An Allied failure to bring sufficient artillery ammunition caused the siege to be prolonged. The garrison repulsed a premature British attempt to storm the fortified convents on 23 June, but finally surrendered four days later after an artillery bombardment breached one fort and set another one on fire. During his maneuvering, Marmont formed the idea that Wellington was only willing to act on the defensive. This mistaken notion would contribute to Marmont's defeat at the Battle of Salamanca a month later.
The Second battle of Przasnysz took place at the beginning of a major Bug-Narew Offensive of the Imperial German army on the German Eastern front. In the course of a stubborn battle, German troops under the command of Max von Gallwitz broke into the heavily fortified defenses of the outnumbered Russian army and took the city of Przasnysz.
First Riga offensive was a military operation of the German Imperial Army with to divert Russian forces from the direction of the main blow of the German summer offensive on Narew River. The Germans broke through the heavily fortified defenses of the Russian army and defeated the vastly superior enemy forces. However, no decisive success was achieved, and at the beginning of August the Russians launched a counteroffensive.
