Scenes of the
Great Wall of China

A View from the Guard Tower

The Qin army invented new weapons to exploit their advantage of their new wall. The most deadly of these was the crossbow that could hurl an arrow 250 yards with amazing accuracy. Other weapons included iron casting techniques to produce double edged swords which would not be known in the west for some 1,300 years later. The soft bronze swords of the enemy were no match for the double-edged iron swords of the Qin army.
