The rolling, chalky Somme countryside is where the French Army brought the German advance to a halt in 1914. The British Army took over a vast swathe of the sector in 1915 and the next year on 1st July 1916, with the French Army, launched the Somme offensive. The first day of the offensive remains the bloodiest day in the history of the British Army, with over 57,000 British and Commonwealth soldiers being killed and wounded. But the battle raged on until November 1916, and it was through experiences gained and lessons learned in the battle that the British Army, made up of men from all over the Empire including Australians, Canadians, New Zealanders, Newfoundlanders, South Africans and Indians, learned to fight. The British Army of July 1916 was a large but inexperienced army. Many of its experienced soldiers were killed or wounded earlier in the war. But it was this inexperienced British Army, fighting alongside the French Army, that would break the back of the German Army on the Western Front in 1916 and go on to become a fighting force capable of leading the rest of the allied armies to victory in 1918. The Somme was a vital and costly training ground for the British Army in 1916, and it was here in 1918 that the Germans pushed back the Allies in the first phase of their final offensive of the war and then the Allies launching the final offensive of the war known as “The Advance to Victory". Even over 100 years after the war finished, vestiges of the trenches and scattered bunkers can still be seen on the battlefields and in memorial parks. The largest British War memorial in the world, the Thiepval Memorial that today commemorates over 72,000 men who were killed nearby and have no known grave, dominates the Somme and can be seen from almost everywhere on the battlefields. The Somme region is also where the Australians, New Zealanders, Newfoundlanders and South African nations commemorate their soldiers that were killed in France and have no known grave.
