What can you tell me about how General Lee influenced the length of the civil war?

Question

I alredy know he was the main southern general, and that Davis undermined his power somewhat. I know Lee's strategy also was useful for the south. What else did he do to lengthen the war?

If possible, could you give me a source as well?

Answer 1

In May 1864, Ulysses S. Grant, the newly appointed commanding general of all Union forces, drove at Lee with enormous superiority in numbers, armaments, and cavalryBeginning at Spotsylvania Court House, Lee had nullified Grant's numbers by using his engineering experience to erect fortifications that were in advance of any fieldworks previously seen in warfare. At Petersburg, Lee extended the field fortifications into permanent lines that presaged trench warfare. While Lee's lines enabled him to withstand Grant's siege of the two cities from late June 1864 to April 1, 1865
He organized Confederate troops into what became the famed Army of Northern Virginia; he tightened command and discipline, improved morale, and convinced the soldiers that headquarters was in full command.
