After defeating the Continental Army under Commander-in-Chief General George Washington at the Battle of White Plains, the British Army forces under the command of Lieutenant General William Howe planned to capture Fort Washington, the last American stronghold on Manhattan. General Washington issued a discretionary order to General Nathanael Greene to abandon the fort and remove its garrison – then numbering 1,200 men but which later to grow to 3,000 – to New Jersey. Colonel Robert Magaw, commanding the fort, declined to abandon it as he believed it could be defended from the British. Howe's forces attacked the fort before Washington reached it to assess the situation.
