The men in the 3rd Texas Infantry were lucky in a way. After Col. James Duff organized the 3rd Texas Infantry from new conscripts and his irregulars in San Antonio, they were camped in various locations along the Texas coast and remained there for the rest of the war and saw no action.
Whilhelm Klier served with the men who were responsible for the massacre of the disloyal Germans who were attempting to leave the Confederacy. I am sure he was not treated with any respect by Duff's irregulars and got every dirty assignment until the war was over.
That was a common practice against most German recruits and residents. In 1862, Col.Peter Hardeman's 1st Texas Cavalry, Arizona Brigade, was raised at Eagle Lake and Columbus in Colorado County with a total of 500 new recruits. Their first duty was to disarm and arrest disloyal Germans in Alleyton and charges of brutality toward some Germans was reported to the general staff.
In 1863, Hardeman's 1st Texas Cavalry was relocated to the Warren Supply Depot (Old Fort Warren) in Fannin County and arrived with only 250 men due to disertions.
