Simon Glancey has submitted the following:
Sgt Field was killed in Catalina Ib FP154 DA-D of 210 Squadron, which crashed in Tonel Bay, near Sagres, Portugal, on an anti-submarine patrol from Gibraltar. The Catalina had been recalled from its mission, but in misty conditions narrowly avoided flying into houses near Sagres, stalled and crashed into the sea. The bodies of two of the crew were recovered, but that of Sgt Field, along with seven fellow crew were not, and their names are listed on the Malta Memorial.
