<span>The arrival of Perry was both a blessing and a curse. Japan had been isolationist for a lengthy period of time and marooned sailors who washed up on the shores of Japan were often mistreated and seen as 'invaders'.

The Battle of Trenton was a key moment of the American War of Independence, as it showed to the American population that the victory was possible.
