The 99th Pennsylvania Infantry was also known as 32nd Volunteers. During the battle of Gettysburg, it served as a member of Ward’s Brigade in Birney’s Division of the Third Corps, Army of the Potomac. The unit was commanded by Major John W. Moore (1836-1865), a native of Philadelphia and eventually killed at battle of Fort Fisher in command of the 203rd Pennsylvania on January 15, 1865. Under his command the 99th brought 339 men to the Gettysburg battlefield and among them, 18 were killed, 81 were wounded and 11 went missing. In total, the 99th Pennsylvania Infantry Regiment lost 9 officers and 113 enlisted men killed and mortally wounded and 1 officer and 112 enlisted men to disease during the Civil War.
The 99th Pennsylvania Infantry Monument, is located 47 feet off of Hancock Avenue, on the right or east side of the road if traveling traveling north. The monument is a 38 feet to the right and rear or southeast of the 
Fitzhugh's Brigade Tablet (MN535) which is along Hancock Avenue. The 114th Pennsylvania Infantry Monument is 153 feet to the rear or due east of the 99th PA infantry monument. The Meade Equestrian Monument (MN690) is 180 feet northeast of this position. This position is also exactly 386 feet northeast of the High Water Mark Monument (MN230). The monument faces due west. This area is an absolute beehive of activity as this site represents the best of what Gettysburg has to offer, both historically and monumentally. Parking is plentiful and is available road-side at intermittently enlarged shoulder cut-outs, usually marked with white striping. Be sure to keep vehicles off the grass or you will be ticketed by park police. I visited this monument on Tuesday, August 7, 2012 at approximately 4:44 P.M. I was at an elevation of 620 feet, ASL. I used a Canon PowerShot 14.1 Megapixel, SX210 IS digital camera for the photos.
There are two monument for this infantry regiment. The primary monument is gorgeous and features a polished tiered and tapered granite monument with bronze state tablet, topped by granite diamond finial. I do not really consider this an important monument (relative to the 1888 sculpture), rather, I look at this as a position marker or stone. These secondary or positions markers are all over the place and allow visitors to have an idea of where all the various units were during the 3-day battle. This position marker howver, is just as beautiful as some of the primary monument on the battlefield.
The Draw the Sword site helped out by the NPS narrative and the SIRIS site offers the following description: Marks position on July 3, 1863. Marker with cornice and polished surface contains a diamond-shaped Corps insignia. Erected by the 99th Pennsylvania Veterans Association and others, it was originally located in 1886 at Houck’s Ridge, later the location of the second monument. It was moved to its present site in 1889. Base 4'-2? sq. shaft of smooth & polished granite, alternating excised & incised lettering. Cap of cyma reversa, ogee, segmental arch, pryamidal cap. Chip in base, some stone staining.
