Multiple cuts Jefferson made had weakened American military strength. With only 16 warships and about 7000 (poorly trained) men ready for action, the United States wasn't ready for war.
The Battle of Washington
In the first days of the war, the British set up a blockade, or the shutting down of a port or road (supplies) from entering or exiting an area, of the American coast. Around the time of 1814, the British navy had about 135 warships blockading American ports.
The Battle of Baltimore
In July, 1812, American Troops, under General William Hull invaded Canada from Detroit. Fearing he didn't have enough soldiers, General Hull became confused. British commander, Isaac Brock, took advantage of this confusion and quickly surrounded Hulls troops. This was a serious defeat for U.S.
The Battle of New Orleans
In August 1814, British troops marched into Washington D.C. Dolly Madison, the first lady, fled with all the important documents and papers. The British set fire to multiple government buildings, including the White House. The British then moved on to Baltimore. First Fort McHenry, which defended the city's harbor. The British ships bombarded through the night of September 13, 1814.
A young American, Francis Scott Key, watched the attack. At dawn, key saw the American flag still flying over the fort. The Americans had beaten the Attack. Later, the idea of a flag flying through the night became a main verse of our national anthem.
U.S. victory against Great Britain, the final major battle of the War of 1812. In the autumn of 1814 a British fleet of more than 50 ships commanded by General Edward Partaken sailed into the Gulf of Mexico and prepared to attack New Orleans and block the Mississippi River.
