Samuel Cole Wright (September 29, 1842 – July 6, 1906) was a sergeant in the Union Army during the American Civil War.
Wright served with the 29th Regiment Massachusetts Volunteer Infantry, participated in 30 battles, was wounded five times and twice reported dead. For his actions during the Battle of Antietam he received the Medal of Honor on January 29, 1896.
Wright initially enlisted as a private in the 3rd Regiment Massachusetts Volunteer Infantry in May 1861 and was transferred to the 29th Massachusetts Infantry when that regiment was formed in December 1861. He participated with the 29th Massachusetts in the Peninsular Campaign during which he was wounded in the head by a shell fragment at the Battle of White Oak Swamp on June 30, 1862.
During the Battle of Antietam on September 17, 1862, the 29th Massachusetts served with the Irish Brigade. As the brigade advanced on the Confederate position at the so-called "Bloody Lane," their progress was impeded by a split rail fence. Brigadier General Thomas Francis Meagher, commanding the Irish Brigade, called for volunteers to tear down the fence.
