Greg,did some more searching on this unit and found this: Company K of the 5th Texas was originally organized as the, "Polk Counrt Flying Artillery" in July 1861 in Livingston, Texas. They formed the unit around a pair of 6 pound cannons. Although trained and organized as artillery, the company was called to service once in Virginia as infantry.
Our firsr Captain was Isaac Newton Moreland Turner (Nick-named Ike). The 6 pound guns were procurred and and donated by Ike's father. Ike Turner led the company and the rest of the regiment during the Maryland Campaign. From Polk County Texas, Turner was the youngest of the original company commanders in the Texas Brigade. He was ony 22 years old. He also had the reputation as a daredevil. At the Battle of Malvern Hill, he led 160 sharpshooters up the hill late in the afternoon. Taking advantage of the setting sun, he and his men were able to disable several Federal batteries by shooting their horses.
Company K was with the 5th Texas and the rest of the Texas Brigade, from the time they arrived in Virginia, till the end of the war. The company saw action in 30 engagements from 1862 through 1865.
