Historical Context

What These Documents Tell Us

These original mission planning maps were the tactical blueprints for September 27, 1944 — a day that became one of the most devastating in Eighth Air Force history.

The Planned Route

Both maps show the meticulously planned route from England to Kassel — waypoints, timing, altitudes, and the rendezvous points where fighters would meet bombers.

The Fatal Error

A navigation error caused the 445th to turn too early near Göttingen, separating them from their fighter escort and sealing the fate of 25 crews.

The Human Cost

In approximately six minutes, 118 American airmen were killed and 121 were taken prisoner — the second-worst single-mission loss in USAAF history.
