The
77th New York Infantry was also known as Bemis Heights Regiment. During the Battle of Gettysburg, it served as a member of Neill’s Brigade in Howe’s Division of the Sedgwick’s Corps, Army of the Potomac. The 77th Regiment, New York Infantry was organized at Saratoga, N. Y., and mustered in November 23, 1861. The regiment mustered out June 27, 1865. The unit was commanded by Lieutenant Colonel
Winsor B. French (1832-1910), a lawyer in Saratoga Springs. French was wounded during the Overland Campaign. In his post-war life he was a District Attorney for Saratoga County. Under his command the 77th brought 424 men to the field and suffered no losses. At Gettysburg the 77th was not closely engaged and proceeded from that battlefield to Fairfield, Pa., Antietam, Marsh Run, Funkstown, Williamsport and Chantilly. During its entire term of service the regiment lost 108 by death from wounds and 176 by death from disease and other causes.
The 77th New York Infantry Monument is located 192 feet to the north of Granite Schoolhouse Lane, up a hill, resting on top and looking down toward the road. The monument is on the left or north side of the road if traveling east along the lane. There is a private home across the street owned by a Gettysburg tour guide who I chatted up for about a half hour or so. 
I was able to park on the other side of the road in front of their house without a problem. I visited this monument on Monday, August 13, 2012 at approximately 12:32 P.M. I was at an elevation of 543 feet, ASL. I used a Canon PowerShot 14.1 Megapixel, SX210 IS digital camera for the photos.
