Rumor of a rupture between the President and Gen. Beauregard—Rebel War Clerk

AUGUST 11th.—There is a whisper that something like a rupture has occurred between the President and Gen. Beauregard; and I am amazed to learn that Mr. Benjamin is inimical to Gen. B. I know nothing of the foundation for the report; but it is said that Beauregard was eager to pass with his army into Maryland, immediately after the battle, and was prevented. It is now quite apparent, from developments, that a small force would have sufficed to take Washington, a few days or weeks after the battle. But was Beauregard aware of the fact, before the opportunity ceased to exist? It is too late now!
