The attention to detail it must have taken for Caesar to have integrated properly the inner and outer siegeworks, and then to have managed the placement and movement of troops within those walls, is just remarkable. A huge testament to the organizational and logistical skills of the legion system.
Agreed. The Gauls had breached the outer wall at one point. He sent his right-hand-man Marc Antony to secure it and then went himself. If the Gauls had breached the outer wall it would have been his last battle and a massacre of his legions. Probably altering the course of Western Civ
