b) Ended by a thunderstorm

The Battle of the Clouds, a lesser-known engagement in the American Revolution, was unique due to its abrupt end by a thunderstorm. This battle, fought in Pennsylvania in 1777, involved American forces led by George Washington clashing with British troops. The sudden storm rendered the muskets inoperable and turned the battlefield into a quagmire, forcing both sides to withdraw. This event underscores the unpredictable nature of 18th-century warfare and the challenges both armies faced in the harsh and varying conditions of the colonial landscape.
