thousand Sicarii terrorists escaped through hidden underground tunnels and sewers, and made their way to Masada, the ancient world’s most impregnable fortress. Located on the edge of the Dead Sea, Masada was built on a 1,500-foot mesa reminiscent of an island of stone in the Grand Canyon. A few narrow paths carved out of the cliff face were the only way up the mountain, which were easy to defend with a small force. The Sicarii surprised the Roman garrison occupying Masada, killing all seven hundred of them, and took over the mountain fortress.
