The prior three years had been a horrific, bloody stalemate near Ypres, with troops in mud-filled trenches—shouting distance apart—under constant artillery bombardment.
In a war remembered for wasteful, senseless carnage, Passchendaele is remembered as one of the worst. A wildly optimistic British plan for quick victory, degraded by weather into a battle of attrition. By the time the fighting slowed (it never actually stopped on the Western Front) in mid-November, over a half million casualties had been suffered by the British, their imperial and commonwealth allies, and Germans.
Nasty little crossroads in that area. Twenty-three years later, there would be a massive evacuation of British troops from Dunkirk, about 40 miles northwest of Passchendaele. And 103 years earlier, Napoleon’s career ended about 90 miles east, near a place called Waterloo.
