"Attention! (Mister) Yamamoto" delivers a wartime mystery with a twist, as Pat Dempsey arrives in a mining town plagued by rumors of ghostly Indians and a sabotaged coal supply. With the fate of a local business hanging in the balance, Pat uncovers a surprising secret beneath the surface—diamonds hidden deep in the earth. Art by Harry Peter and inks by Henry Kiefer bring the eerie atmosphere to life, while Kiefer’s cover captures the tension with a striking, shadowed portrait of the enigmatic Yamamoto.

Daniel Boone (in spirit)Harding (flier)Richards (flier)

Two American fighter pilots, Harding and Richards, return from a mission over the South Pacific to find a Japanese freighter below—but with no bombs to drop, they improvise a daring trick using what little they have on hand. Meanwhile, a contingent of U.S. Marines executes a surprise attack at Viru Harbor, landing under cover of darkness and circling behind enemy positions to silence their gun batteries and turn the tide of battle. These tales showcase the resourcefulness and courage that define American fighting spirit in the Pacific theater.

Staff Sergeant Benjamin Warmer

Staff Sergeant Benjamin Warmer, a towering aerial gunner from San Francisco, proves why he's earned his "Demon" nickname when over 100 Nazi Messerschmitts ambush a squadron of American bombers on a mission over Sicily. As the Luftwaffe descends on the vastly outnumbered Yanks, Warmer mans his waist gun with deadly precision, methodically taking down enemy fighters one after another in a breathtaking display of marksmanship and nerve.

Sergeant Walter J. Bodt

Sergeant Walter J. Bodt's courage on the hills of Guadalcanal saves two platoons from certain defeat, but a sniper's bullet leaves him gravely wounded and fighting for his life in a New Guinea hospital. When doctors pronounce him dead, Bodt's remarkable will to survive kicks in—the same determination that earned him the Navy Cross in battle. This wartime tale of a young Marine's refusal to give up is both a testament to his bravery and a celebration of the doctors who brought him back from the brink.
