By the latter part of that month, General McClellan, in command of an army of more than one hundred thousand men, landed on the Peninsula between the James and York Rivers, and after stubbornly-contested engagements with the forces of General Johnston, advanced up the Peninsula--the Confederates slowly retiring. In the latter part of May, a portion of the Federal forces had crossed the Chickahominy, and confronted General Johnston defending Richmond.Such was the serious condition of affairs in the spring of 1862.
