In the early morning fog of July 5, 1944, the USS Sunfish broke free from a curtain of gray and found herself staring at a rare, eerie clarity over the northern Kuril Islands. Aradio To rose sharply in front of her like a black tooth jutting from the sea, and for the first time in days, the crew could see clearly. Paramushiru, Shimushu, even Kamchatka were all laid out under a hazy sun that had barely burned through the mist. The weather gave them a moment of visual advantage, but it also left them exposed. There was no Japanese shipping in sight, but that didn’t mean it wasn’t out there. In these waters, silence could kill.
