March 5 in Military History

British soldiers fired into a crowd of colonists outside the Custom House on King Street in Boston, killing five men. The incident became a rallying point for the American independence movement and was exploited by patriot leaders like Samuel Adams and Paul Revere to inflame anti-British sentiment throughout the colonies.

On the twelfth day of the Siege of the Alamo, Mexican forces under General Santa Anna completed their encirclement of the former mission. Colonel William Barret Travis, co-commanding with Jim Bowie (who was bedridden with illness), sent out his last courier with a desperate plea for reinforcements. The final assault would come the following morning.

President Lincoln formally promoted Ulysses S. Grant to the rank of Lieutenant General, a rank previously held only by George Washington. The promotion made Grant the commanding general of all Union armies. Grant immediately began planning the coordinated multi-front offensive strategy that would ultimately end the Civil War within a year.

President Woodrow Wilson was inaugurated for his second term, having won re-election partly on the slogan "He kept us out of war." Yet within a month, Germany's resumption of unrestricted submarine warfare and the Zimmermann Telegram would compel Wilson to ask Congress for a declaration of war on April 2, 1917, bringing America into World War I.

The prototype Supermarine Spitfire (K5054) made its maiden flight from Eastleigh Aerodrome near Southampton, piloted by Captain Joseph "Mutt" Summers, chief test pilot for Vickers. Upon landing after the eight-minute flight, Summers famously said "don't touch anything," wanting the control settings preserved for consultation with designer R.J. Mitchell. The Spitfire would become the most iconic British fighter of World War II.

Soviet secret police chief Lavrentiy Beria presented a proposal to Joseph Stalin and the Politburo to execute 25,700 Polish prisoners of war, military officers, police, intellectuals, and other leaders held in Soviet camps since the 1939 invasion of Poland. Stalin and the Politburo approved the order. The executions, carried out in April and May 1940, would be concealed for decades and blamed on Nazi Germany.

The Gloster E.28/39, Britain's first jet-powered aircraft designed by Frank Whittle's team, had already flown in 1941. By March 1943, work on the twin-engine Gloster Meteor, the first operational British jet fighter, was well underway, with the first prototype making taxi tests. The Meteor would become the only Allied jet aircraft to see combat in World War II.

Brigadier Orde Wingate launched Operation Thursday, the largest airborne invasion in the China-Burma-India Theater. Approximately 9,000 Chindits, British and Indian long-range penetration troops, were flown by glider and transport aircraft into jungle clearings deep behind Japanese lines in Burma to establish fortified strongholds and disrupt enemy communications.

As elements of the U.S. 3rd Armored Division's Task Force fought into the streets of Cologne, Germany, one of the war's most famous tank duels took place near the iconic Cologne Cathedral. A brand-new M26 Pershing heavy tank engaged and destroyed a German Panther tank in a dramatic duel captured on film by combat cameramen, footage that remains among the most viewed tank combat film of World War II.

Former British Prime Minister Winston Churchill delivered his famous "Sinews of Peace" address at Westminster College in Fulton, Missouri, with President Harry Truman on the platform. Churchill declared that "an iron curtain has descended across the Continent," warning that Soviet expansion threatened the freedom of Central and Eastern Europe. The speech is widely regarded as marking the public beginning of the Cold War.

Soviet dictator Joseph Stalin died at his Kuntsevo dacha outside Moscow at the age of 74, following a stroke suffered on March 1. His death ended nearly three decades of brutal totalitarian rule, triggered a power struggle within the Soviet leadership, and led to significant shifts in Cold War dynamics including the eventual policy of de-Stalinization under Nikita Khrushchev.

U.S. Army troops of the 101st Airborne Division fought fierce engagements in and around the A Shau Valley in Vietnam. The valley, a major conduit for North Vietnamese troops and supplies moving south along the Ho Chi Minh Trail, was the site of repeated American incursions throughout 1969 as part of operations to interdict enemy supply lines.

In the aftermath of the Gulf War ceasefire declared on February 28, coalition forces continued processing the massive influx of Iraqi prisoners of war. By early March, more than 86,000 Iraqi soldiers had surrendered, the largest mass capitulation since World War II, overwhelming the capacity of prisoner-of-war camps and requiring emergency logistics measures.

During Operation Anaconda in Afghanistan's Shah-i-Kot Valley, intense fighting continued on Takur Ghar mountain (Roberts Ridge). Navy SEAL Neil Roberts had fallen from a helicopter on March 4, and rescue teams fought desperate battles against entrenched al-Qaeda fighters at over 10,000 feet elevation. Seven Americans were killed in the fighting on the mountain, making it one of the deadliest engagements of the early Afghanistan war.
