Query: Relentless

Bass recounts the story of a troop of sometimes reluctant, but always relentless men ostensibly fighting for their new nation of Texas. The historical incident, obscure to most of us, is well known to Texans, the retaliation for the Battle of San Jacinto. We come to know what drives some of them and the regrets of others. Mostly, we marvel at their capacity for survival. When everything is taken away from them; when they live day after day in toil and torture, infested with an army of lice and tested by disease after disease, they still have the ability to experience the small joy that comes with the minutest reprieve.There is little joy in reading the book, though the author presents the story as well we could expect. Like castor oil, though, it may be good for us to see those so eager for war get their wish, then regret it for every minute of their lives.
