The
149th Pennsylvania Infantry Monument served as a member of Stone’s Brigade in Doubleday’s Division of the First Corps, Army of the Potomac, a Fighting 300 Regiment. The unit was commanded by
Colonel Walton Dwight (1837-1878). Dwight was in the lumber business in Coudersport. He was wounded during the first day at Gettysburg on July 1. He was a post-war mayor of Binghamton, New York. Under Dwight's command, 450 men were engaged and among them 53 were killed, 172 were wounded and 111 went missing. The 149th Pennsylvania Infantry Regiment lost a total of 4 officers and 160 enlisted men killed or mortally wounded and 172 enlisted men to disease during the Civil War. It is honored by three monuments at Gettysburg.
The 
149th Pennsylvania Infantry Monument is located on the right or east side of Hancock Avenue (RD310) if traveling north along the road. The monument is 62 feet east of the road in the grass. The monument is also located 68 feet northeast of the Battery C, 5th U.S. Artillery - US Regulars Tablet (MN683-B). 
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 3:31 P.M. I was at an elevation of 576 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: Smith Granite Company, fabricator. (I saw the foundry stamp on the side of the monument). Dedicated Oct. 20, 1886. Rectangular, horizontal monument contains a relief of a uniformed Union solider lying behind and among a broken fence and rocks. He is aiming his rifle with proper right hand on the trigger. The I Corps emblem is carved into the ends of the die.

The monument was dedicated October 20, 1886 by the Commonwealth of Pennsylvania. The monument is composed of Westerly granite and has the following dimensions: The sculpture is approximately 3 feet 1 inch x 5 feet 7 inches x 2 feet and the base is approximately 1 foot 8 inches x 7 feet 3 inches x 3 feet 8 inches. The monument was fabricated by the Smith Granite Company out of Westerly, Rhode Island. The fact Westerly granite was used for the monument and it was manufactured by the Smith Granite Company is no coincidence. Smith Granite Company In 1845 Orlando Smith discovered a granite outcrop on the property owned by Joshua Babcock in Westerly, Rhode Island, and a year later purchased the site from him. He established a granite quarry shortly there after and by the 1850s was cutting granite monuments. In 1887 the Smith Granite Company was incorporated, with family members holding all the stock.. There are simple incised inscriptions on the front and sides which list the name and order of battle for this regiment, all of which read:
(Front):149th Reg't Pa. Vol's
July 3rd 1863.

2nd Brigade
