Wanted Johnny Texas (1967)

Johnny Texas is recruited by the U.S. Army to find a safe passage for a wagon train and impatient settlers to the West. Johnny figures his best bet is to pay off the local band of desperadoes helmed by a psychotic outlaw. When that doesn't work, Colonel Stewart orders Johnny to attack a fortress and detonate a secret stash of dynamite. Source: SWDB www.spaghetti-western.net
