Black Week │ October 9, 1943
Target │ Anklam, Marienburg, Danzig and Gdynia
VIII BC Mission #113
Dispatched 338 B-17s and B-24s to 4 targets
Of that, 3BD 96 B-17s hit the Focke-Wulf aircraft plant at Marienburg that produced nearly 50% of the FW-190s used by the Luftwaffe (GAF).
Rest of the Story: The specific strike mission against Marienburg was noted as the best example to date of daylight precision bombing by the 8th in the air war against Germany. The mission was a 1,500 mile trip with 10 hrs of flying. The weather over Marienburg was perfect with little counter-air activities by the GAF and FLAK was almost non-existent. These conditions allowed the B-17s to conduct bomb release altitude between 11-13,000 ft. The B-17s dropped nearly 218 tons of 500lb & 100lb jellied oil bombs with accuracy of some 58% of mu*****ns within 1,000 ft of the target and some 83% within 2,000 ft. Two B-17s were lost at Marienburg.
Lessons Learned: 8thAF bombings at Marienburg, caused confidence to soar among its leaders and crews. British Air Chief Marshal Portal declared the B-17 bombing at Marienberg as the “most perfect example of accurate distribution of bombs.” Leaders of 8thAF released post-strike photos of Marienburg to the press to boost confidence in daylight precision bombing and to counter the push by the RAF to move all aerial bombardment to night.
For 8thAF, Marienburg provided a false sense of comfort that fighter escorts were not needed. The subsequent air battles over Munster (10-10-43) and Schweinfurt (10-14-43), clearly demonstrated fighter escorts were necessary to allowing bombers to concentrate on accurate aerial bombardment. These 2 air battles subsequent to Marienburg, also showed that the GAF was a learning organization. The GAF was adjusting to larger bomber formations of 8thAF, and started re-thinking their counter-air and FLAK tactics and techniques.
