Public debate surrounded Tennessee's decision to join the Confederacy and both the Confederate and Union armies recruited soldiers from the state. More than 100,000 men from Tennessee served with the Confederacy and over 31,000 served with the Union. Forrest posted advertisements to join his regiment, with the slogan, "Let's have some fun and kill some Yankees!". Forrest's command included his Escort Company (his "Special Forces"), for which he selected the best soldiers available. This unit, which varied in size from 40 to 90 men, constituted the elite of his cavalry.
