April 10 in U.S. military history

1941: When Germany invades Denmark, Greenland (a Danish colony) asks for U.S. military protection.

1942: A day after surrendering to Japanese Forces, an estimated 80,000 U.S. and Filipino prisoners of war begin the six-day, 85-mile “Bataan Death March.” Despite 14th Army commander Gen. Masaharu Homma’s orders that POWs be treated peacefully, the captives suffer extreme physical abuse, are given little to no food and water, and thousands are murdered or die from starvation or disease on their journey.

1972: B-52 bombers strike North Vietnamese targets (SAM-2 sites near Vinh), the first bombing missions flown north of the Demilitarized Zone since 1967.
