During the war of 1812 the british were defeated in every attack on the united states except in

a)baltimore and detroit
b)montreal and new york
c)florida and new orleans
d)maine and washington, d. c.

The correct answer is the letter A.

Here is a brief explanation:

The War of 1812, also known as the Anglo-American War, was the war between the United States and the United Kingdom and its colonies, including Upper Canada, Lower Canada, Nova Scotia, Bermuda and New land.  

On October 1, 1812, the Battle of Detroit occurred, where American General William Hull surrendered to British-Canadian general Isaac Brock and the British captured the village of Detroit without firing a single shot. Though fewer in number, they had threatened an overwhelming defeat, and Hull surrendered.

On September 12th, the British fleet approached Baltimore via North Point, near the mouth of the Patapsco River. A troop of about 4,500 of its men marched to Baltimore while its warships went up along the Patapsco river and advanced toward Fort McHenry. These ships opened a twenty-five hour bombing at the fort, but their American commanders refused to surrender.
