The Battle of the Clouds was a failed attempt to delay the British advance on Philadelphia during the American Revolutionary War on September 16, 1777, in the area surrounding present day Malvern, Pennsylvania. After the American defeat at the Battle of Brandywine, the British Army remained encamped near Chadds Ford. When British commander William Howe was informed that the weakened American force was less than ten miles (16 km) away, he decided to press for another decisive victory.

The Philadelphia campaign (1777–1778) was a British military campaign during the American Revolutionary War designed to gain control of Philadelphia, the Revolutionary-era capital where the Second Continental Congress convened and formed the Continental Army and appointed George Washington as its commander in 1775, and authored and unanimously adopted the Declaration of Independence the following year, on July 4, 1776, which formalized and escalated the war.
