I. The Unbearable Sight: A Convoy’s Last Moments
For the Japanese Imperial Navy, the transit through the Bismarck Sea was supposed to be routine. It was early March 1943. Eight troop transports, laden with nearly 7,000 soldiers destined to reinforce the besieged Japanese fortress in New Guinea, sliced confidently through the water, shielded by four modern destroyers. This convoy was the lifeblood of their Pacific defense—a conveyor belt of men and materiel. They were safe. The American bombers flew high, and their bombs always missed.
Then, the scream from a lookout sliced through the tropical morning air. He wasn't pointing at the distant clouds where the B-17s usually lumbered. He was pointing straight ahead, at the water.
Approaching at terrifying speed, just fifty feet above the wave tops, were dark shadows that should not exist. They were American B-25 Mitchell bombers, but they were flying in a way that defied every known military doctrine—at mast height, at eye level. As they roared closer, their sleek, modified noses erupted, not with the flash of a single gun, but in a horrific, concentrated solid wall of white-hot tracers.
What followed was not a bombing run; it was, in the words of one surviving American pilot, "an ex*****on." In the span of fifteen minutes, the Japanese Imperial Navy watched in frozen horror as its entire force was annihilated. Eight transports and four destroyers—twelve ships—were ripped to pieces. Nearly 3,000 men were killed. This was not war; it was an act of erasure perpetrated by a weapon that, by all logic, history, and military doctrine, should have been impossible.
