01Caesar's inner wall (contravallation) was 11 miles; his outer wall (circumvallation) was 14 miles — both built in under six weeks.

03When the relief army failed, Vercingetorix surrendered 80,000 starving survivors — and the 20,000 Mandubii civilians Caesar had refused to feed died in the gap between the walls.
