Those Keeping Lincoln Out of Richmond
Winfield Scott was keenly aware of the capabilities of the Southern officers who fought under him in Mexico, and did not hesitate to inform Lincoln of who it was opposing the conquest of Richmond.

Those Keeping Lincoln Out of Richmond:

"Abraham Lincoln once asked General [Winfield S.] Scott the question: 
"Why is it that you were once able to take the City of Mexico in three months with five thousand men, and we have been unable to take Richmond with one hundred thousand men?
"I will tell you," said General Scott. "The men who took us into the City of Mexico are the same men who are keeping us out of Richmond."
