The answer is B: had twice as many soldiers as Lee.
The siege of Petersburg was a decisive Yankee victory which led to the retreat and surrender of confederate Gen. Robert E. Lee. The victory by the union at Petersburg meant that Lee would be forced into a role not familiar to the fantastic Southern commander. If General Lee would have a larger army, a few good peers, and more support, he could possibly have extended the war. However, the war was over and the Siege of Petersburg sealed everything.
