During the week spent at Alexandria, Banks was for the first time in direct and comparatively rapid communication with Grant, now in the very heart of his Vicksburg campaign, and here, as we have seen, the correspondence was brought to a point. When he first learned that Grant had given up all intention of sending to him any portion of the Army of the Tennessee, Banks was greatly cast down, and his plans rapidly underwent many changes and perturbations. At first he was disposed to think that nothing remained but to retrace his steps over the whole toilsome way by Opelousas, the Teche, Brashear, New Orleans, and the Mississippi River to Baton Rouge, and thence to conduct a separate attack upon Port Hudson. This movement would probably have consumed two months, and long before the expiration of that time it was fair to suppose the object of such an operation would have ceased to exist. What led Banks to this despondent view was the fact that he had been counting upon Grant's steamboat transportation for the crossing of the Mississippi to Bayou Sara, and at first, he did not see how this deficiency could now be met.

Indeed, on the 12th of May, he went so far as to issue his preparatory orders for the retrograde movement; but the next day careful reconnoissances by his engineers, Major Houston and Lieutenant Harwood, led him to change his mind and to conclude that it would, after all, be possible to march to Simmesport, and there, using the light-draught boats of the Department of the Gulf, supplemented by such steamers as Grant might be able to spare for this purpose, to transfer the whole column to Grand Gulf and thence march to join Grant in the rear of Vicksburg. Accordingly, on the 13th of May, Banks gave orders for the immediate movement of his whole force in accordance with this plan, and set aside all the preparations that had previously been made.

When the news reached Washington that Grant had gone to Jackson and Banks to Alexandria, great was the dissatisfaction of the Government and emphatic its expression. On the 19th of May Halleck wrote to Banks:

"These operations are too eccentric to be pursued. I must again urge that you co-operate as soon as possible with General Grant east of the Mississippi. Your forces must be united at the earliest possible moment. Otherwise the enemy will concentrate on Grant and crush him. Do all you can to prevent this. . . .

"We shall watch with the greatest anxiety the movements of yourself and General Grant. I have urged him to keep his forces concentrated as much as possible and not to move east until he gets control of the Mississippi River."

And again, on the 23d of May, still more pointedly:

"If these eccentric movements, with the main forces of the enemy on the Mississippi River, do not lead to some serious disaster, it will be because the enemy does not take full advantage of his opportunity. I assure you the Government is exceedingly disappointed that you and General Grant are not acting in conjunction. It thought to secure that object by authorizing you to assume the entire command as soon as you and General Grant could unite."

When the despatches were penned, Grant and Banks were already committed to their own plans for the final campaign on the Mississippi. When they were received, Grant was before Vicksburg, Banks before Hudson; each had delivered his first assault and entered upon the siege. The censure was withdrawn as soon as, in the light of full explanations, the circumstances came to be understood.

See also Smith to Cooper, April 23d: "The people at Fort De Russy cannot stand a land attack. The advance of the enemy's column to the Hauffpaur . . . will ensure its speedy fall, with loss of guns and garrison. Under these circumstances, General Taylor has ordered the removal of the 32-pounder rifle and 11-inch columbiads to a position higher up the Red River."
