The Battle of Jericho, as described in the Bible's Book of Joshua, marked the first battle fought in the Israelites' conquest of Canaan. The battle is famous for the triumphant fall of Jericho's walls, brought on about by marching Israelites blaring their trumpets. However, outside of the Bible, there is a fierce debate over whether walls of Jericho's fell in the time described by the Old Testament.
