The Battle of the Clouds (also known as the Battle of Warren, Battle of Whitehorse Tavern, or the Battle of Goshen) is an aborted engagement of the Philadelphia campaign of 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 remains encamped near Chadds Ford.
When British commander William Howe is informed that the weakened American force is less than ten miles (sixteen kilometers away, he decides to press for another decisive victory.
George Washington learns of Howe's plans, and prepares for battle.
Before the two armies ca fully engage, a torrential downpour ensues.
Significantly outnumbered, and with tens of thousands of cartridges ruined by the rain, Washington opts to retreat.
Bogged down by rain and mud, the British allow Washington and his army to withdraw.
