The Battle of the Trench, also known as the Battle of Khandaq and the Battle of the Confederates, was part of the conflict between the Muslims and the Quraysh, where this time the Quraysh took the offensive and advanced on the Muslims, who defended themselves in Medina by digging a trench around their settlement at the suggestion of Salman the Persian. The battle, which took place in 627 and lasted around two weeks, was lightly fought, with the Muslims reported to have suffered five to six casualties and the Quraysh three.
