The 14th Connecticut Infantry served as a member of Smyth’s Brigade in Hays’ Division of the Second Corps, Army of the Potomac, a Fighting 300 Regiment. The 14th Connecticut was organized at Hartford, Connecticut, on August 23, 1862, and mustered into the volunteer army. The 14th helped repulse the Confederate attack on the third day known as Pickett's Charge. The unit was commanded by Major Theodore G. Ellis (1829-January 9, 1883). Ellis trained as an engineer in Boston, and by 1854 was working in Hartford, CT. He mustered in on 23 August 1862 as Adjutant of the regiment.. After the war, Ellis was the Surveyor General of Connecticut. Under his command, the 14th had 200 men engaged at Gettysburg and among them 10 were killed, 52 were wounded and 4 went missing.
The 14th Connecticut Infantry RIght Flank Monument is located along 
Hancock Avenue (RD310), on the left or west side of the road if traveling traveling north and is 188 feet to the right or north of the primary monument. One would need to face west to read the monument, in the direction of the once advancing enemy of July 3, 1863. The monument is diagonally across the road from the Hancock's U.S. 2nd Corps Headquarters Marker and 413 feet due south of the Abraham Brian Barn. 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 available at intermittently enlarged shoulder cutouts on the right side of the road. Be sure to keep vehicles off the grass or you will be ticketed by park police. I visited the monument on Monday, August 13, 2012 @ 5:39 PM, EDT & @ an altitude of 634 feet, ASL. I used a Canon PowerShot 14.1 Megapixel, SX210 IS digital camera for the photos.
Often, state regiment monuments are also accompanied by secondary monument which designate flank positions maintained from July 1-3, 1863 as well as flank monuments to delineate the ends of troop lines. Presumably, this position marker was dedicated at the same time as the 14th Connecticut Infantry Monument, July 2, 1893. This lone flank marker for the 14th Connecticut is composed of granite, and is about 4 feet high and a foot and a half wide and deep, looking like a perfect rectangular prism except for the top which is slanted downward. The inscription on the slanted top reads 14 C.V. which means the 14th Connecticut Infantry. There is an inscription on the front long side which reads Right of Reg't July 2, 3 & 4 1863. To the rear of the marker is a stone wall protected by some wooden pickets. Additional details from the nomination form concerning the flank monuments may be found below in red.

** Incidentally, the NRHP got the picture wrong on their nomination form. The picture shown is NOT the picture of this sculpture. The picture is actually of the third day position marker located at the Bliss Barn Site. Ironically, SIRIS got it right. **
