October 21 in History

British and Australian troops from the 27th Commonwealth Brigade engaged the North Korean 239th Regiment in fierce combat at Yongju, blocking a key enemy withdrawal route during the UN advance northward. The engagement demonstrated the effectiveness of Commonwealth forces in the Korean War and helped secure the road to Pyongyang.

Crusader armies began the siege of Antioch with no siege equipment. The city's walls were 30 feet high and studded with 400 towers. The Crusaders had no navy to blockade the port. Food kept coming in. The siege lasted seven months. Starvation killed more Crusaders than combat. They finally entered through a betrayed gate. Then they were besieged inside it.

Colonists in Taunton, Massachusetts, raised a flag with the word 'Liberty' sewn on it in 1774 — the first known use of the word on an American flag. The flag was red. They raised it on a 112-foot liberty pole in defiance of British rule. The pole stood until 1777, when a storm knocked it down. The town replaced it. The current liberty pole is the fifth.

Lord Nelson's British fleet shattered the combined French and Spanish armada at Trafalgar, ending Napoleon's dream of invading England. This decisive victory secured British naval dominance for a century while claiming Nelson's life in the process.

Austrian General Mack surrendered 30,000 troops to Napoleon at Ulm in 1805 without a major battle. He'd been outmaneuvered in six days. Napoleon's army had marched 200 miles in two weeks, circling behind the Austrians before they realized it. Mack was court-martialed and imprisoned. Napoleon called Ulm his finest strategic victory. He fought Austerlitz seven weeks later.

Reverend Hutchings founded the Penang Free School in 1816 in a rented house with 20 students. It was the first English-language school in Southeast Asia. Tuition was free for children of all races and religions — radical for colonial Malaya. The school moved buildings five times as enrollment grew. It's still operating. Alumni include prime ministers, chief justices, and a Nobel laureate.

Union forces under Colonel Edward Baker crumble against Confederate troops at Ball's Bluff, shattering Northern hopes for a quick victory. This disastrous defeat claims Baker's life and forces Washington to reorganize its command structure, directly leading to the creation of the Joint Committee on the Conduct of the War.

Southern Plains tribes signed the Medicine Lodge Treaty in 1867, agreeing to move to reservations in western Oklahoma. Kiowa, Comanche, Cheyenne, and Arapaho leaders touched pen to paper near Medicine Lodge Creek, Kansas. In exchange, the government promised food, schools, and protection from white settlers. The promises weren't kept. Within two years, tribes were starving. Red River War followed in 1874.

In 1879, Thomas Edison tested the first practical electric incandescent light bulb using a carbonized thread filament, which lasted 13½ hours before burning out. This invention was a critical moment in the development of electric lighting, revolutionizing how people illuminated their homes and workplaces, and paving the way for modern electrical engineering.
