21st Texas Cavalry also know as the 1st Texas Lancers. Now the Lancer idea didn't really work out probably because the regiment was made up of volunteers most of whom were quite capable with guns and horse but had never used a sword much less a lance. As a some time historic fencer and reenactor I can say that its much easier to learn the use of a gun then a sword.
Based on what I have read Confederate cavalry preferred pistols and shotguns to sword so its no surprise the lances got lost pretty quick still its a fun idea for the gaming table. The two lance armed stands will almost certainly be my fist casualties.
Not knowing the units actual colors I used a Texas state flag
Pistols are the best close range weapon for Civil War cavalry
