I am grateful to the hon. Gentleman for that contribution. He makes a wise point with his customary eloquence, and I am sure it will be echoed across the House.
The battle was infamous not only for the terrible conditions but for the sheer scale of the losses. In the region of 250,000 allied soldiers and around the same number of German soldiers, a total of some 500,000 men from both sides, were wounded, killed or missing. Those are quite frankly unbelievable numbers. Fought between 31 July and 10 November 1917, the battle saw the British Army attempt to break out of the notorious Ypres Salient and put intolerable pressure on the German defences. Troops from across Britain and Ireland took part, along with significant numbers from today’s Commonwealth, particularly from Australia, Canada, New Zealand and South Africa. Allied air forces played an important role, providing vital reconnaissance for the ground forces and fighting deadly dogfights with their German counterparts in the skies above the trenches. The battle was conceived, in part, as a means of influencing the struggle against German submarines, and the Royal Naval Division served on Passchendaele’s battlefield alongside other soldiers. Many others contributed during the battle and in the fighting around Ypres during the conflict, including servicemen from India and the West Indies, labourers from China and, of course, the nurses and medical staff who worked behind the lines to treat the wounded.
For all those who fought in that small corner of Flanders in the late summer and autumn of 1917, including those in the Belgian, French and German armies, it would prove to be one of the most gruelling experiences of the conflict. Much of the first world war’s enduring photography, poetry and artwork was inspired by the desolate landscape, which became a featureless quagmire over the course of the battle. After periods of intense rain, the mud became so bad that men and animals could be swallowed up in the swamp. Images, such as the photography of Frank Hurley or the evocative paintings of Paul Nash, are a harrowing reflection of the utter devastation that was wrought.
Many families, villages and towns were touched by the fighting. In Wales, the battle is partly remembered for the loss of the renowned poet Ellis Evans—better known by his bardic name Hedd Wyn—who died on Pilckem Ridge on the opening day of the battle.
