The Colonel's Lady - Clifton Adams- Clifton Adams

Reardon is an ex-Confederate officer. The war is over, and, at the start of the book, he's on his way out west to join the US Army. Joining the cavalry out west isn't much different to a prison sentence. It is a remote post, surrounded by hostile Indians, with extremely limited food, drink and access to the ladyfolk. It is normally the last respite of desperate men. Reardon's reason is also his weakness - he spotted his ex-love, Caroline, on the arm of an army colonel. Keen to see her again her, he joins the regiment. The book follows his training and his first few missions as a scout.
