Guns for Garcia — Ramsay Thorne

Dick Walker. Ex-U.S. soldier. Framed for murder. Wanted for desertion by the U.S. Army. He's a tough, two-handed straight-shooter with a taste for victory. And war is the only game he's willing to play...
Exiled from his native country he roams through the shifting battle zones of Latin America -- the best soldier of fortune in the business. And he's known as Captain Gringo.
Now, at the end of the nineteenth century, the Spanish are taking over Cuba. The Americans are supplying arms to the Cuban freedom fighters. And ten tons of weaponry and ammo are in the hands of Captain Gringo, the one man who has the grim task of carrying the load through Spanish-occupied territory. And the bad luck to face his deadliest foe -- “Butcher” Weyler -- the Spanish general who's launching a bloody gambit to end Captain Gringo's career ...
