On the 1st of July Davis joined Farragut with four gunboats and six mortar-boats of the Mississippi fleet. On the 9th Farragut received orders from the Navy Department, dated on the 5th, and forwarded by way of Cairo, to send Porter with the _Octorara_ and twelve mortar-boats at once to Hampton Roads. Porter steamed down the river on the 10th. This was obviously one of the first-fruits of the campaign of the Peninsula just ended by the withdrawal of the Army of the Potomac to the James. Indeed, at this crisis, all occasions seemed to be informing against the Union plan of campaign, and the same events that drew the Confederate armies together served to draw the Union armies apart. Just as we have seen Pope called away from Fort Pillow on the eve of an attack that must have resulted in its capture, and taken in haste to swell the slow march of Halleck's army before Corinth, so now, when for a full month Corinth had been abandoned by the Confederates, Halleck's forces were being broken up and dispersed to all four of the winds, save that which might have blown them to the south. Halleck declared himself unable to respond to Farragut's urgent appeal for help. "I cannot," he said, when urged by Stanton; "I am sending reinforcements to General Curtis, in Arkansas, and to General Buell, in Tennessee and Kentucky." Not only this, but he was being called upon by Lincoln himself for 25,000 troops to reinforce the Army of the Potomac before Richmond. "Probably I shall be able to do so," Halleck told Farragut, "as soon as I can get my troops more concentrated. This may delay the clearing of the river, but its accomplishment will be certain in a few weeks."
