I don’t suppose you have any evidence to support that statement do you?
And don’t say: “he lost”. Had Lee been in Grants position the war would not have lasted as long as it did.
for starters, to have been in Grant’s position, he would have had to remain loyal to the United States. He could have been in that position, but for one minor fact. U.S. Grand remained loyal to the United States. Lee chose to devote his loyalty to the State of Virginia. Lee lost.
He offered his sword up in surrender to General Grant at Appomattox. Lee lost, get over it.
