Germantown, October 4th, 1777.
After the Battle of Brandywine, Washington was eager to force another encounter with Howe. The American army was still between Howe and Philadelphia, and Washington wanted to keep it that way.

This was effected on the 20th and the British bayoneted about 300 Americans in an event known as the Paoli Massacre, losing only about six of their own men.

Howe had divided his forces, so that at Germantown
