The United States Army has made the sacrifices that keep our nation free. Since its humble beginnings, it has grown, through lean times and flush, to become the premier fighting force in the world. It is the oldest and most senior branch of the U.S. military in order of precedence. And today is the Army’s birthday!
The U.S. Army began its life as the Continental Army before the United States of America was established as a country. What is now the U.S. Army was created by the Second Continental Congress on June 14, 1775, in order to fight the British during the American Revolution. The Battle of Lexington and Concord with the “shot heard ’round the world” had taken place just weeks earlier. The Battle of Bunker Hill, where the upstart colonist militias showed they could hold their own against the British military, would take place just three days later on June 17, 1775. So, yes, the U.S. Army is actually older than the United States itself.
After the defeat of the British at Yorktown and the United States’ independence, the United States and Great Britain would fight against each other again during the War of 1812. (Now, the two countries are the closest of allies having fought together during World Wars I and II, Korea, and the Global War on Terror.)
As the U.S. began its expansion westward, the Army was responsible for mapping nearly all of the territory and protecting American interests and citizens as they moved into new territories.
