Captain Jed Foster is more than a thief. He's a traitor. With a handful of murderous rogues, he's run off with four wagons containing new Springfield 1880 rifles, bayonets, and ammunition meant to resupply the troops at Fort Bowie in Arizona Territory. Foster plans to sell the weapons to the highest bidder whetherer it's Apaches, Mexican revolutionaries, or Confederate veterans who still dream of destroying the Union. But that's the least of Foster's problems. His junior officer, Lieutenant Grat Holden, is coming after him. If Holden can't bring the renegade to justice, he'll face court-martial for losing the wagons. If he's caught crossing the Mexican border, the U.S. Army will deny knowledge of the mission. Holden can't do it alone. With the help of an ornery ex-sergeant known as "Hard Rock" Masterson and fiery guerilla fighter Soledad, the young lieutenant will have to face off with war chiefs, banditos, and cutthroat outlaws.
