The position marker for the right flank of the infantry of the Army of the Potomac is southeast of Gettysburg on Neil Avenue. It is often called “Lost Lane” because of its inaccessibility. The position marker is near the monument to the 61st Pennsylvania Infantry, which was the right flank of its brigade. The regiment’s right flank marker is next to the position marker.
The Right Flank
On July 3 Neill’s Brigade of the Sixth Army Corps was ordered to protect the Army of the Potomac’s main supply line on Baltimore Pike. Confederate skirmishers were drifting down from the fighting around Culp’s Hill. Neill formed his brigade and advanced to the present location of Neill Avenue. He drove back the Confederates while taking a handful of casualties.
Although this was the right flank of the infantry, there were Federal troops east of the position. Cavalry pickets stretched out for several miles east of Gettysburg, where a large concentration of cavalry guarded the flank. The marker for the Extreme Right Flank of the Army is about three miles away (as the crow flies) on the East Cavalry Battlefield.
Location of the marker to the Right of the Infantry of the Army of the Potomac at Gettysburg
The monument and marker are southeast of Gettysburg on Neil Avenue. This small strip of public land is almost totally surrounded by private property. Public access is by an unmaintained narrow right of way. It starts from the end of Clapsaddle Road and heads southwest about 400 yards. It then turns back southeast another 130 yards to the western end of Neil Avenue. In the past the legal right of way has been completely blocked by downed trees and thorn bushes. It is very easy to miss the turn and end up trespassing. (39°48’28.9″N 77°12’33.9″W)
