For what reason did we impress our soldiers in 1812 and what was the effect of it?

So, this is an odd question (unless you live in the UK).

I am an American, and impressment was largely used against American sailors by the British.

Impressment was the policy of capturing a ship and forcing the sailors to work for you. The British were the masters of it and it was super embarrassing for the American Navy.

The US made the British swear to stop in a treaty but it was a major cause of tensions leading up to the War of 1812.
