11 May, 1944, the 354th FG was escorting heavies - target Saarbrucken. 1st Lt. Clayton Kelly Gross leading Green flight , 355th FS, was weaving on the right side of one section of B-17s. He spotted a large formation of ME-109s a few thousand feet above and right and paralleling the bomber course. With wingman Billie D. Harris he began a climb to a position behind the enemy fighters. 'Checking Six' he discovered a second group of enemy aircraft trailing bringing the total to an estimated 70. Slowing and watching the second group pass over without observing him, they then climbed into a position very close to the enemy rear, "Two into Seventy - Lets get 'em".
Gross and Harris both flamed the first targets and moved on to others. Their tracers and probable radio chatter by the victims caused the entire group to break up. Gross then hit a second victim who bailed out. An enemy attack diverted! Kelly would finish the mission with 2 victories and 1 probable and the war with 6 victories, 1 probable, and 4 damaged.
