Peninsula Campaign of 1862
Lincoln preferred an overland campaign toward Richmond, but McClellan proposed an amphibious maneuver in which the Union Army would land on the Virginia Peninsula, effectively circumventing the rebels under General Joseph E. Johnston.
McClellan put his Peninsula Campaign into action in March 1862, landing over 120,000 men on the coast and proceeding east toward the Confederate capital. The Confederates withdrew toward Richmond, and McClellan’s troops fought their way to within only a few miles of the city.
Despite his strong position, McClellan failed to capitalize on his tactical advantage, once again believing that he might be outnumbered. When General Robert E. Lee took control of Confederate forces on June 1, he launched a series of bold offensives that culminated in the Seven Days Battles.
Okay, so you'e claiming the Peninsular Campaign as a whole as a time McClellan had superior numbers and failed to win a "Lincoln-style" victory.
So here's the problem. The Peninsular Campaign has several individual phases.
Yorktown: McClellan had the numerical advantage at Yorktown, but it was not as great as is often stated and the Confederates reinforced quickly - actually quicker than the Union could. There was no point when McClellan had enough of an advantage to simply roll over the enemy, and because the Warwick line was a strongly garrisoned river line an attack would largely have been futile with the force ratios McClellan actually possessed. Despite this McClellan compelled the abandonment of the position after a month.
When Grant had a similar advantage at Vicksburg to the one McClellan had the first day or two at Yorktown and ordered an attack, he failed to take the fortifications. In fact, I'm not aware of any Civil War situation where an army broke through a flankless defensive line at the odds present.
Williamsburg: McClellan attacked the Confederate positions and won a victory.
Chickahominy (Seven Pines): McClellan at this point had only a very minor numerical advantage (no more than 10% or so), and his orders forced him to split himself across the Chickahominy. He was thus unable to muster the manpower for an offensive, and no other AoTP commander won an offensive battle at those odds either.
Chickahominy (Seven Days): McClellan was outnumbered.
Harrisons Landing: McClellan's force at Harrisons Landing and Lee's force at Richmond were comparable, with Lee's force in entrenchments.
Essentially there's no point where McClellan had means (a numerical advantage) and method (a place to apply it where in a comparable situation another Union commander won a victory).
