On May 14, 1943, the first B-26 mission in the ETO took place. It was a low-level mission to a power plant at Ijmuijden in the Netherlands:
12 B-26's are dispatched against the Velsen power station at Ijmuiden, The Netherlands; 11 hit the target at 1100 hours; 1 B-26 is damaged beyond repair when it crashes upon returning to base and 9 others are damaged; casualties are 1 KIA and 7 MIA. .... The attack at Ijmuiden is made at low level by the 322d Bombardment Group (Medium), the first US medium bomber group to become operational in the UK.
