Continuation of 20/21 May; this page photographed before frame 00698 containing 19/20 and 20/21 May. Air Force Mammut Jobourg tracked enemy convoy 0804–1040 from upper-right BF3147 via 3148, 3149, 3146 to centre 3154; 1006–1050 from left-edge centre BF3148 to upper centre 3145; 1137–1610 from lower-right corner BF2369 via 3147, 3148, 3145, 3146, 3154 to centre 3155. FuMO51 Cap de la Hague II detected same targets, but over shorter area. Normandy interception network sea-target bearings 0017–0245 from upper-left corner BF3198 via 3529 (0134) to upper-right corner 3551. Radars confirmed contacts. These bearings enabled early direction of radars and artillery fire. Further bearings 0230–0540 from upper-right edge BF3561 via 3553, 3529, 3524 to right centre 3532. Individual interception bearings in sea area off Cotentin agreed with detections. One locating signal for navigational assistance.
