Shot down 6 March 1943 in B-17F 42-5378, 306BG/367BS while serving as Co-Pilot. The aircraft had developed an oil leak in no. 3 engine over the channel, but oil pressure stayed steady so pilots continued mission toward the submarine pens at Lorient, France. According to Strong, Fighters attacked as this plane was dropping back due to the earlier oil leak and the fact this Group was in the low Squadron. When engine 4 quit, bailout was ordered. Biggs delayed opening his chute. Landing in the Lorient area without shoes, he improvised. Helped, sheltered, clothed, fed and transported by French citizens and members of the Résistance, he crossed the Pyrénées mountains into Spain on 5 June 1943 and was flown from Gibraltar back to England on June 28, 1943. Evaded (EVD). His evasion is documented in his Escape & Evasion Report # 41 which may be viewed at: https://catalog.archives.gov/id/5554681
