Narrative - Official Air Force Mission Description
Four radar-equipped B-24s of the 329th Bombardment Squadron (Heavy), 93d Bombardment Group (Heavy) fly a "moling" or intruder, mission aimed at harassing the enemy in weather unsuitable for large missions by alerting air-raid crews in the area north of the Ruhr. The 329th has been in training for these operations since 14 Dec. This mission and two subsequent missions in Janauary are foiled by clear weather over the target area. Twenty Spitfire Mk Vs of the 4th Fighter Group are dispatched on fighter patrols. HQ 2d Antisubmarine Squadron (Heavy) with B-24s is established at St. Eval, England upon arrival from the U.S.
