The
5th Wisconsin Infantry served as a member of Russell’s Brigade in Wright’s Division of the Sixth Corps, Army of the Potomac, a Fighting 300 Regiment. While @ Gettysburg, the infantry unit was commanded by
Colonel Thomas S. Allen (July 26, 1825 - December 12, 1905). Under his command this regiment had 491 men who served at Gettysburg and among them no casualties were reported. The 5th Infantry was assembled at Camp Randall, in Madison on July 12, 1861. The 5th Wisconsin Infantry initially mustered 1108 men and later recruited an additional 832 men, for a total of 1940 men.The regiment suffered 15 officers and 180 enlisted men killed in action or who later died of their wounds, plus another 2 officers and 132 enlisted men who died of disease, for a total of 329 fatalities.
Allen became Colonel of the 5th Wisconsin Infantry Regiment on January 26, 1863, commanding the regiment at Marye's Heights, Rappahannock Station, where he was wounded for a second time on November 7, 1863, and Petersburg. He mustered out on August 2, 1864. For his service he was brevetted Major General of United States Volunteers at the end of the war.In 1866 Allen was elected Wisconsin Secretary of State on the Republican ticket for a four-year term. In 1869 he helped organize the Grand Army of the Republic in Wisconsin, and served as commander of the Wisconsin department for two years.In 1870 he moved to Oshkosh, becoming a partner in the Oshkosh Northwestern until 1884. From 1885 until 1902 he published the Wisconsin Telegraph, a German newspaper. He died on December 12, 1905 in Oshkosh, Wisconsin.
The 5th Wisconsin Infantry Monument is lat the very end of the very short Howe Avenue @ the cul-de-sac and is on the left or north side of the road it traveling southeast toward the cul-de-sac. As a point of reference if traveling north on Taneytown Road, and if at the intersection, a left turn is Wright Avenue and a right turn is Howe Avenue. The tablet stands next to the 
9th Pennsylvania Infantry Monument (MN379-B), then the Russell's Brigade - US Brigade Tablet (MN496) and furthest away, the 6th Maine Monument (MN 378) which are to the left or west of this site, the first listed monument being the closest. There are a string more of these monuments on the same side of the road, leading back to the intersection. 
Parking is available at the end of Howe Avenue in the cul-de-sac just a few feet away. There is no other room to park on this road as there are no shoulders and it accommodates two way traffic. I visited this site on Monday, July 1, 2013 on the 150th anniversary of the Battle of Gettysburg @ 1:15 PM, EDT & @ an altitude of 464 feet, ASL. As always, I used my trusty and oft abused 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: Monument consists of two-tiered rough-hewn base, polished and rough-hewn shaft and a finial of the Corps insignia of the Greek cross. Monument is a granite shaft topped with the Sixth Corps Greek Cross and set on a 6×4.6 foot rough hewn double base. The shaft has polished panels with inscriptions. Overall height is 14.2 feet. Flanking markers are 1.6×1.2 foot with flat tops that contain raised polished letters.
The 5th Wisconsin Infantry Monument was dedicated on June 30, 1888 by the State of Wisconsin. The monument is composed of red and white granite, probably Wisconsin red granite. The sculpture is approximately 14 feet 2 inches x 3 feet 10 inches x 2 feet 3 inches and the base is approximately 6 feet in width and 4 feet in depth. I could not recover any information as to the artisans employed to create this sculpture/monument. There are inscriptions on the front and back which read:
(Front Inscription):5th Wis. Vol.
Gettysburg July 2, 3, 4, 5
3d Brig. (Russells')
