Below is an excerpt from a letter written to general McClellan commander of the Union Army. Why did Lincoln have a McClellan replaced as commander of the union army?

Lincoln had McClellan replaced as commander of the Union Army because of McClellan's cautious and slow approach to warfare. McClellan's hesitancy to engage the enemy and his failure to aggressively pursue the Confederate forces frustrated Lincoln and other leaders. Additionally, McClellan's reluctance to follow Lincoln's directives and his strained relationship with the President contributed to his removal from command. Ultimately, Lincoln believed that a more decisive and proactive leader was needed to effectively lead the Union Army to victory.
