Lowe went on to serve in the Peninsula Campaign of 1862, making observations over Mechanicsville, Virginia, and the ensuing Battle of Seven Pines or Fair Oaks. This particular battle marks a pivotal moment where conflicting intelligence reports between Lowe (in the air) and Pinkerton (scouting on the ground) gave vastly different accounts on the number of Confederate troops. It is believed that had McClellan valued Lowe's intelligence over Pinkerton's, the Confederacy could have been dealt a "knockout blow" to its forces.
