The second consecutive day the same four carrying out this patrol, the day previous took off at 13:40 hrs returning at 15:40 hrs seeing nothing but a suspected E-Boat.

They made landfall at Den Helder, Holland, and flew south sighting the convoy a short while later (2). The pilots climbed to 500’ to take photos and were just turning for home when they were attacked by about 8 enemy aircraft, including Me109Gs and FW109s.

The dog fight lasted 8 minutes and F/O. Pigg (2) was the only one to return. He made a head-on attack on a FW190, but did not observe the results and suffered damage to his own propeller. He then made 2 attacks on a ME109 and saw it dive into the sea. He also saw one Mustang with glycol streaming from it making for the Dutch coast and another aircraft, which was possibly a Mustang, dive into the sea. Unable to make radio contact with the others he turned for home and landed at Coltishall.’
