The Roman Ramp
After seeing the vertical sides of Massada one wonders how the Roman Army could have captured it. Well look at this picture a wonder no more.
The Romans built a ramp up one side of the mountain. They were clever these Romans for the defenders of Massada could have very easily killed any one working on the ramp but they didn't. The ramp builders were bran new slaves that the Romans had captured at Jerusalem. Jews built the ramp for the Roman army and the defenders of Massada would not kill their fellow country men and women.
In the end the defenders committed suicide rather than be captured by the Romans.
