Operator 5 #37: The Coming of the Mongol Hordes - Paperback

by Curtis Steele (Author), Emile C. Tepperman (Author), Harry Fisk (Illustrator)

Through Pennsylvania's ravished countryside thundered that ruthless Mongol cavalcade, its goal the sacking of New York! The severed heads of patriots dangled from their leaders' blood-stained saddles, and in their wake rumbled dread, primitive machines of death. Barring their advance was only that little band of patriots at Valley Forge. But on that sacred battleground, while Operator 5 fought to save a girl from being hurled to death by a giant catapult, and civilization was being turned back to the Dark Ages by a horde of Asiatic vandals-America struck against a Yellow Dictatorship for the freedom of the world!
