He felt that our armies would gain more renown and secure greater victories if the "Riot Act" could be read, and both Houses of Congress dispersed to their homes at the very earliest moment.
General Halleck, who had command of the Western Department, became anxious for reputation on the field, and was thought by many to be jealous of the daily increasing fame of General Grant.

After the battle of Shiloh, he took command in person of the army which Grant had already rendered illustrious, leaving Grant to command its right wing.

Uniting the Western forces into one large army General Halleck marched southward in pursuit of the Confederate column now under the command of Beauregard, and strongly intrenched at Corinth.
As the army approached, Corinth was evacuated, and the campaign of General Halleck, leading to no important engagement, did not add to his military fame.

Meanwhile there had been increasing dissatisfaction in Congress and among the people with the supersedure of General Grant, and to relieve the situation General Halleck was called to Washington in the early part of July to take command of the army which had been relinquished by McClellan in March, when he set forth upon the Peninsular campaign.

In the intervening months there had been no General-in-Chief of the army, the duties being performed by the Secretary of War.
GENERAL GEORGE B.McCLELLAN.
The Western victories, important as they were, did not remove the pressure in the East.
