Battle of Monongahela (1755)

On 9th July 1755 amid the wilderness of North America, Britain suffered one of the most humiliating defeats in her history. General Braddock's army, a mixture of British regulars and American Militia, was devastated, losing over 900 men from a force of 1,300. General Braddock was killed and the remnants of his army were rescued by his aide, Colonel George Washington. This defeat and subsequent chain of events ultimately led to the start of the Seven Years' War.
