March 2 in Military History

General George Washington ordered Continental Army artillery to begin bombarding British positions in Boston from Lechmere Point and other positions. Using cannons that Colonel Henry Knox had hauled 300 miles from Fort Ticonderoga through the winter, the three-night bombardment served as a critical diversion for the secret fortification of Dorchester Heights on March 4-5.

President Thomas Jefferson signed the Act Prohibiting Importation of Slaves, banning the Atlantic slave trade effective January 1, 1808, the earliest date permitted by the Constitution. Enforcement was delegated to the U.S. Navy, making it one of the service's earliest law enforcement missions, though enforcement remained chronically underfunded for decades.

While roughly 200 defenders held the Alamo against thousands of Mexican troops, 59 delegates at Washington-on-the-Brazos signed the Texas Declaration of Independence, creating the Republic of Texas. The convention also named Sam Houston, celebrating his 43rd birthday, commander-in-chief of the Texas army.

Brigadier General George Armstrong Custer's cavalry annihilated the remnants of Confederate Lieutenant General Jubal Early's command at Waynesboro, Virginia, capturing over 1,200 prisoners, all of Early's artillery, 17 battle flags, and 150 supply wagons. The victory eliminated the last Confederate presence in the Shenandoah Valley.

Congress overrode President Andrew Johnson's veto to pass the First Reconstruction Act, dividing ten former Confederate states into five military districts governed by Army generals with sweeping authority. The act required new state constitutions guaranteeing Black male suffrage and ratification of the 14th Amendment before readmission to the Union.

Congress passed the Platt Amendment as a rider to the Army Appropriations Bill, asserting the right of the United States to intervene militarily in Cuba and prohibiting Cuba from entering treaties that impaired its sovereignty. The amendment also ceded the naval station at Guantánamo Bay to the United States, a base it still operates 125 years later.

President Woodrow Wilson signed the Jones-Shafroth Act, granting U.S. citizenship to all residents of Puerto Rico. The timing, just weeks before the United States entered World War I, was deliberate: as citizens, Puerto Ricans became subject to the military draft, and approximately 20,000 would serve in the war.

In Allied-occupied southern Italy, freight train No. 8017, overloaded with approximately 600 stowaways, stalled inside a two-kilometer tunnel near Balvano. Carbon monoxide from the locomotive's poor-quality wartime coal killed 517 people, the deadliest rail disaster in Italian history, a direct consequence of wartime supply shortages and infrastructure collapse.

The Vietnamese National Assembly elected Ho Chi Minh as President of the Democratic Republic of Vietnam, formalizing the government that would fight two of the twentieth century's most consequential wars, first against France, then against the United States.

General Ne Win, Chief of Staff of the Burma Defense Forces, overthrew the democratically elected government of Prime Minister U Nu in a swift morning coup, arresting the prime minister and other civilian leaders. The coup established military rule that would persist in various forms for over five decades.

Over 100 U.S. Air Force and South Vietnamese aircraft launched the first strikes of Operation Rolling Thunder, attacking military targets in North Vietnam. The campaign, intended to coerce Hanoi into ceasing support for the Viet Cong, would last three and a half years, drop 864,000 tons of bombs, and become one of the most controversial military operations in American history.

Two days after President Bush declared a ceasefire, the U.S. Army's 24th Infantry Division under Major General Barry McCaffrey engaged a large column of retreating Iraqi Republican Guard near the Rumaila oil field. McCaffrey's force destroyed over 180 armored vehicles and 400 trucks in under two hours with no American casualties, one of the most lopsided armored engagements in history and one of the war's most controversial.

Russian forces completed the capture of Kherson, a Ukrainian regional capital of 290,000 people, making it the only major Ukrainian city to fall during the 2022 invasion. The city controlled access to water supplies for Crimea and was strategically vital for control of southern Ukraine. Ukraine would recapture it eight months later.
