LOOS-EN-GOHELLE, France (AP) — Scotsman William McAleer had been in France barely two months when, just before sunrise on Sept. 25, 1915, he was among thousands of other troops who launched the British army’s largest attack so far of World War I.

By the next day, the 22-year-old private from a seaside town in Fife was dead. Almost 60,000 British troops died in the Battle of Loos, and a third disappeared with no known grave.
