December 8 in Military History

After a disastrous series of defeats in New York and New Jersey, General Washington's badly depleted Continental Army crossed the Delaware River into Pennsylvania, taking or destroying all available boats to prevent British pursuit. Barely 3,000 effective troops remained, many with enlistments expiring in weeks. The desperate crossing set the stage for Washington's famous Christmas night re-crossing that would turn the war's momentum at Trenton.

President Lincoln announced his "Ten Percent Plan" for Reconstruction, offering full pardons to most Confederates who took an oath of allegiance to the United States and accepted the abolition of slavery. When ten percent of a seceded state's 1860 voters took the oath, that state could form a new government and rejoin the Union, a remarkably lenient approach that drew fierce opposition from Radical Republicans in Congress.

A Royal Navy squadron under Vice-Admiral Doveton Sturdee intercepted and destroyed Vice Admiral Maximilian von Spee's German East Asia Squadron off the Falkland Islands, avenging the British defeat at Coronel six weeks earlier. The engagement was the first significant British naval victory of the First World War and shut down surface raiding by German cruisers in the southern oceans.

President Franklin D. Roosevelt appeared before a joint session of Congress and delivered one of the most consequential speeches in American history. Speaking for just six minutes, Roosevelt declared that "yesterday, December 7, 1941, a date which will live in infamy, the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan." The Senate approved the declaration 82-0 and the House 388-1, with only Jeannette Rankin of Montana, a pacifist who had also voted against entering World War I, casting the sole dissenting vote.

In coordinated strikes across the Western Pacific, Japanese forces landed in Malaya, bombed Clark Air Base in the Philippines, destroying most American aircraft on the ground, and attacked Hong Kong, Guam, and Wake Island. The simultaneous offensives, all occurring on December 8 local time west of the International Date Line, established Japan's bid for the Greater East Asia Co-Prosperity Sphere.

Japanese naval and ground forces began the invasion of Guam just hours after the Pearl Harbor attack. The small US Marine and Navy garrison, lacking heavy weapons or air support, held out for two days before surrendering, losing the first American territory captured in the Pacific War.

Seventh Air Force B-24 Liberators flying from Saipan struck Iwo Jima for the first time, opening a 72-day preparatory bombing campaign that preceded the Marine Corps landings in February 1945. The sustained attacks were intended to soften Japanese defenses but ultimately demonstrated the limits of air interdiction against heavily entrenched positions.

President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev signed the Intermediate-Range Nuclear Forces Treaty at a Washington summit, eliminating an entire class of nuclear weapons, all ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. It was the first arms control agreement to reduce, rather than merely limit, nuclear arsenals.

President Ronald Reagan and General Secretary Mikhail Gorbachev signed the Intermediate-Range Nuclear Forces Treaty at the White House, eliminating an entire class of ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. It was the first arms control treaty to actually destroy weapons rather than cap their numbers.

The leaders of Russia, Ukraine, and Belarus signed the Belavezha Accords in a hunting lodge in western Belarus, declaring the Soviet Union dissolved and creating the Commonwealth of Independent States. The agreement ended the Cold War adversary that had justified forty-five years of American strategic nuclear planning and conventional force posture.
