Jack Armstrong #12

Jack Armstrong encounters enemy soldiers on an island and sets a trap using trip-wire vines that detonates the general's booby trap, turning it against the enemy forces. The grateful general acknowledges that the Americans are too clever for his guerrilla warfare tactics and realizes his entire island army has been compromised. The issue also includes a "Sports Champs" feature about Alfred Letourner, a former six-day racing star who pedaled a specially equipped bicycle at 108 mph near Bakersfield, California, along with bicycle riding tips, and a historical adventure story titled "Desperate Mission" set during the War of 1812 in Canada.
