when did the battle of vimy ridge start
Battle of Vimy Ridge The Battle of Vimy Ridge was a military engagement fought primarily as part of the Battle of Arras, in the Nord-Pas-de-Calais region of France, during the First World War. The main combatants were the Canadian Corps, of four divisions, against three divisions of the German Sixth Army. The battle, which took place from 9 to 12 April 1917, was part of the opening phase of the British-led Battle of Arras, a diversionary attack for the French Nivelle Offensive.
First Battle of the Marne The Battle of the Marne (French: Première bataille de la Marne, also known as the Miracle of the Marne, Le Miracle de la Marne) was a World War I battle fought from 6–10 September 1914.[1] It resulted in an Allied victory against the German armies in the west. The battle was the culmination of the German advance into France and pursuit of the Allied armies which followed the Battle of the Frontiers in August and had reached the eastern outskirts of Paris. A counter-attack by six French armies and the British Expeditionary Force (BEF) along the Marne River forced the Imperial German Army to retreat north-west, leading to the First Battle of the Aisne and the Race to the Sea. The battle was a victory for the Allies but led to four years of trench warfare stalemate on the Western Front.
