Yesterday I had to get plates for my new car. Instead of getting the plain old standard plates I got plates for the 4th Infantry Division, based at Fort Carson in Colorado Springs. I thought the plates were more interesting plus it supports our troops. Additionally there is a Civil War connection.
The 4th has four brigades and in each brigade is an infantry battalion, the fourth brigade has two battalions. These infantry battalions trace their history to the Civil War. There are two battalions of the 8 and 12th Infantry Regiments. Both units served with the Army of the Potomac. There is one battalion of the 22nd Infantry Regiment, which actually started its history as the 2nd Battalion of the 13th Regiment. The 13th Regiment's motto is "First at Vicksburg" although it appears that the 2nd battalion spent more of its time in Missouri than in the army under Sherman and Grant.
There are also three squadrons of the 10th Cavalry Regiment, the Buffalo Soldiers, in the division but that's a post war regiment.
