Your source for information on the American War of Independence
After the British abandoned Boston, William Howe replaced Thomas Gage as the British supreme commander in North America. Howe led the highly successful invasion of New York City in the summer of 1776. However, he was severely criticized for a lack of aggressiveness and was dogged by rumors of being soft on the rebels. In the following year, Howe captured the rebel capital of Philadelphia and defeated the Patriot Army at the battles of Brandywine and Germantown. After wintering in Philadelphia, the British replaced Howe with Sir Henry Clinton and Howe returned to Britain where he attempted to refute charges of poor generalship and to improve his reputation.
