Martin Caidin wrote a very cool book about this day called 'Black Thrusday' .. a great read.
Some have disputed his details, but it's a very good look at operations, offense, defense, escort, .. in the dark days before the Mustang arrived.
The 8th AF took huge losses on this mission, the Luftwaffe was on top of their game on this day, it was truly War in the Air over Germany.. on this day.
