The lull in the American war has come at last

to an end. General Banks has advanced from New Orleans to Shreveport on the Red River, but was there attacked by the Confederates and -compelled to retreat, with a loss of some 2,000 men. He appears -to have fallen back upon his gunboats, and the Confederates, re- newing the attack at a point commanded by the vessels, suffered almost as severe a loss. The disaster has put a stop to active exer- tions in the south-west. In Virginia, however, it is under- stood that General Grant has completed his preparations, and that a combined attack is to be made on Richmond across the Rappa- hannock and up the Peninsula. The Government has prohibited the transmission of all war news from the scene of action, and it may be another mail or two before we have any decisive in- telligence.
