In August 1914, Europe's major powers threw themselves into war with gleeful abandon. Germany, a rising power with vast aspirations, plowed across Belgium, seeking to checkmate France quickly before Russia could mobilize, thereby averting the prospect of a two-front war. Thousands of young Germans, anticipating a six-week conflict, boarded troop trains singing the optimistic refrain: "Ausflug nach Paris. Auf Widersehen auf dem Boulevard." ("Excursion to Paris. See you again on the Boulevard.")
As losses mounted and the stalemate hardened, war fever began to dissipate on both sides. Many of those pressed into service on the Western Front had not succumbed to the initial frenzy of bloodlust. Fighting alongside French, Belgian, and English troops were Hindus and Sikhs from India, as well as Gurkhas from the Himalayan Kingdom of Nepal.
