Lincoln, and the country, were disappointed by the failure of McClellan’s peninsula campaign. Lincoln had removed McClellan from overall command of Union forces back in March; rather than restore him to that command, he gave it to Halleck, as the officer nominally responsible for the Union successes in the west. Command in the west passed to Halleck’s second-in-command, U.S. Grant.
