On June 28, 1863 Major General George G. Meade was awakened in his tent just outside of Frederick, Maryland by a courier from President Lincoln ordering him to take command of the Federal Army of the Potomac. With Robert E. Lee’s Army of Northern Virginia deep into an invasion of Pennsylvania and Federal forces scattered in pursuit, it was a surprising and stressful scenario for Meade, who had proven himself as a dependable division and corps commander throughout the war. Nevertheless Meade led the Army of the Potomac into his native Pennsylvania and engaged Lee three days later in a decisive victory at Gettysburg.
A monument (below) and two wayside markers interpret what happened here in 1863:

Location of the monument and markers
The monument and markers are on the southwest side of Frederick on the north side of Himes Avenue at the intersection with Mansion Drive. Although next to where all the major freeways come together they can be tricky to get to. The best access from the freeways seems to be taking exit 11 of southbound US 15, whose exit ramp turns into Himes Avenue.
