The 72nd Pennsylvania Infantry was also known as Baxter’s Fire Zouaves. During the battle of Gettysburg, it served as a member of Webb’s Brigade in Gibbon’s Division of the Second Corps, Army of the Potomac, a Fighting 300 Regiment and was part of the famous Philadelphia Brigade. They wore a very Americanized zouave uniform, consisting of a zouave jacket trimmed with red without a tombeux on the jacket, sky-blue trousers with a red stripe down the leg, a sky-blue zouave vest trimmed in red, white gaiters, and a dark blue kepi. The jacket was decorated with 16 ball brass buttons down the front of the jacket, which were not part of the original French Zouave uniform.
The 72nd was recruited from among the firemen of Philadelphia, Pennsylvania in early August 1861.At the Battle of Gettysburg, it defended the Angle on July 2 and 3. On the evening of the 2nd, it helped defeat Confederate Brigade General Ambrose R. Wright's attack, advancing just over the stone wall. The next day, it was placed in reserve for the brigade near the copse of trees. During Pickett's Charge, its position served as a rallying point for the left wing of the 71st and two companies of the 106th Pennsylvania, which had been driven back.
The 72nd Pennsylvania Infantry was commanded by Colonel Dewitt C. Baxter (1829-1881) @ Gettysburg. At Gettysburg, Col. Baxter replaced the wounded General Webb in command of the Brigade, and Lt. Colonel Hesser replaced him in command of the 72nd Regiment. After the war, Baxter was a naval officer at the Custom House from 1867-1871. In the mid-1870s he was involved in the Keystone Portable Forge Company. He also may have revived his Panoramic Directory business in the late 1870s. Upon his death in May 1881, his obituary reported, Baxter was holding "a position at the Custom house." He died on May 9, 1881, and his obituary appeared on the front-page the following day in the Philadelphia Public Ledger. He was originally buried in Monument Cemetery in Philadelphia, but later he was reinterred in Lawnview in 1956. Under Baxter's command, the 72nd brought 458 men to the battlefield and among them, 44 men were killed, 146 were wounded and 2 went missing.
The 72nd Pennsylvania Infantry Monument is located on the left or west side of 
Hancock Avenue (RD310) if traveling north along the road at an area called The Angle. The monument is 204 feet from the road, resting in the grass, 180 feet west northwest of the High Water Mark of the Rebellion Monument (MN230), and in front of the Copse of Trees. On this side of the road there are about 1080 feet of green fields with a line of monumentation spread across it representing the line of union regiments who defended Cemetery Ridge at The Angle against Longstreet's assault also referred to as Pickett's Charge on July 3, 1863, the final day of the Great Battle. This is the last monument in that long line of monumentation. 
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 4:43 P.M. I was at an elevation of 602 feet, ASL. I used a Canon PowerShot 14.1 Megapixel, SX210 IS digital camera for the photos.
The Draw the Sword site helped out by the NPS narrative and the SIRIS site offers the following description: Uniformed Fire Zouave soldier stands on a rough plinth on a square, tiered base. Holding his weapon in both hands, he swings it over his proper right shoulder, as though preparing to strike. The Seal of the State of Pennsylvania in relief is affixed to the lower front of the base. The base has bronze tablets. The shaft has an incised inscription. Erected by the surviving members of the 72nd Pennsylvania Infantry, Philadelphia Brigade in memory of their deceased members. The sculpture indicates the position held by the 72nd Pennsylvania, Philadelphia Brigade on July 3, 1863, where they stood in line and fired volleys into Armistead’s line as he advanced across the angle wall. The only monument at Gettysburg that was subject to a fight that went all the way up to the Pennsylvania Supreme Court. The 72nd had selected a location 283 feet away from where the GBMA wanted it. They went to court and the Commonwealth ruled in favor of the 72nd. About 1000 people attended the 1891 statuary dedication, and Edward McPherson accepted the monument for the GBMA
The monument was dedicated in July 4, 1891 by the surviving members of the 72nd Infantry. The monument is composed of granite w/ bronze relief as well as the bronze statue and has the following dimensions: The sculpture is 13 feet 6 inches in height and the base is approximately 5 feet 9 inches in height by 4 feet 9 inches². The statue was sculpted by someone named Stephens. I do not know the first name. I took a picture of his name he wrote on the base of the statue and the date, 1888. The monument was designed by J. Reed and manufactured at the Bureau Brothers foundry, a well-known founder if you are familiar with the monumentation about this park. The 2011 "Gettysburg" quarter was developed with an image of the 72nd's statuary monument "in consultation with representatives of Gettysburg National Military Park". There are inscriptions on all four sides of the monument incised in the polished granite which reads:
