The Pacific Transit Zone That Slowly Collapsed Under Attack

Описание: The East China Sea was never meant to be a battlefield. It was a transit corridor—a 400-mile-wide artery carrying oil, iron ore, coal, and food from Japan’s conquered territories to the factories of the Home Islands. But between March 1944 and June 1945, this vital shipping lane slowly collapsed under sustained submarine attack, and with it, Japan’s ability to continue the war.

In this documentary, we examine how American submarines turned the East China Sea into a systematic interdiction zone during the Pacific War. More than 212 Japanese cargo ships and tankers attempted to cross this corridor. Seventy-three were sunk. Nearly 284,000 tons of shipping vanished beneath the surface. What began as isolated torpedo attacks evolved into a campaign of cumulative attrition. Gato-class submarines exploited shallow depths, poor sonar conditions, and predictable convoy routes to intercept formation after formation. A March 19, 1944 strike demonstrated the vulnerability of the route. By mid-1944, multiple submarines were operating simultaneously across the zone. In February 1945, a heavily escorted twelve-tanker convoy suffered catastrophic losses in a single afternoon, crippling already desperate fuel reserves.

This was not one decisive naval battle. It was sustained geographic control. Convoy warfare in the East China Sea became a slow-motion blockade that strangled Japanese logistics. Refineries ran dry. Industrial output plummeted. Naval operations were curtailed. The campaign shows how submarine warfare and convoy interdiction reshaped the Pacific Theater through relentless pressure rather than dramatic spectacle.

On this channel, we explore the overlooked naval campaigns of World War II and the strategic decisions that changed the course of history.
