The 'Philadelphia campaign' (1777–1778) was a
British initiative in the
American Revolutionary War. The campaign was controversial because, although British General
William Howe successfully captured the revolutionary capital of
Philadelphia, he proceeded slowly and did not aid the concurrent
Saratoga campaign further north, which ended in disaster for the British. General Howe resigned during the occupation of Philadelphia and was replaced by his second-in-command, General Sir
Henry Clinton, who evacuated Philadelphia in order to reinforce
New York City.
Capture of Philadelphia
Having secured New York City in his
1776 campaign, in 1777 General Howe concentrated on capturing Philadelphia, the seat of the Revolutionary government. He moved slowly, landing 15,000 troops in late August at the northern end of
Chesapeake Bay, about 55 miles (90 km) southwest of Philadelphia. General
George Washington positioned his 11,000 men between Howe and Philadelphia but was
outflanked and driven back at the
Battle of Brandywine on
September 11,
1777. The
Continental Congress once again abandoned the city, hastening to
York, Pennsylvania. British and Revolutionary forces maneuvered around each other for the next several days, clashing in minor encounters such as the so-called "
Paoli Massacre." On
September 26, Howe finally outmaneuvered Washington and marched into Philadelphia unopposed.
After taking the city, the British
garrisoned about 9,000 troops in
Germantown, five miles (8 km) north of Philadelphia. Washington
unsuccessfully attacked Germantown in early October, and then retreated to watch and wait. Meanwhile, the British secured the
Delaware River by taking forts
Mifflin and
Mercer in November. In early December, Washington successfully repelled a British attack at the
Battle of White Marsh.
General Washington's problems at this time were not just with the British. In the so-called
Conway Cabal, some politicians and officers unhappy with Washington's recent performance as commander-in-chief secretively discussed his removal. Washington, offended by the behind-the-scenes maneuvering, laid the whole matter openly before Congress. His supporters rallied behind him, and the episode was abated.
Valley Forge and Monmouth
Washington and his army encamped at
Valley Forge in December 1777, about 20 miles (32 km) from Philadelphia, where they stayed for the next six months. Over the winter, 2,500 men (out of 10,000) died from disease and exposure. However, the army eventually emerged from Valley Forge in good order, thanks in part to a training program supervised by
Baron von Steuben.
Meanwhile, there was a shakeup in the British command, with General Clinton replacing Howe as commander-in-chief.
France's entry into the war had changed British war strategy, and Clinton was ordered by the government to abandon Philadelphia and defend New York City, now vulnerable to French naval power. Washington's army shadowed Clinton on his withdrawal and forced a
battle at Monmouth on
June 28,
1778, the last major battle in the North. Washington's second-in-command, General
Charles Lee, ordered a controversial retreat during the battle, allowing Clinton's army to escape. By July, Clinton was in New York City, and Washington was again at
White Plains, New York. Both armies were back where they had been two years earlier. With the exception of scattered minor actions in the North, like the
Battle of Stony Point, the focus of the war shifted elsewhere.
