Jeaff Greswell made RAF history on the night of 3/4 May 1942, when he carried out the first successful night attack on a surfaced submarine using the newly introduced Leigh Light. Then a flight commander in No 172 Squadron he was flying Wellington ES986, when his radar operator picked up a radar contact. Successfully homing onto the contact he used the light to illuminate the Italian submarine Luigi Torelli which was recharging its batteries on the surface and carried out an attack which crippled the boat. Although not sunk, it was prevented from submerging and was later captured, repaired and put into service with the Royal Navy. His co-pilot on this occasion was Allan Triggs, who would later be awarded the VC for carrying out an attack on a German U-boat.

He later commanded No 179 Squadron, also equipped with Wellingtons after which he was promoted to Group Captain and sent to the USA to take delivery of a secret weapon and accompany it back to the UK. The weapon in question was the first acoustic homing torpedo, and to maintain the secrecy of its existence, had been named the 'Mark 24 Mine'. However, having safely delivered his cargo to the appropriate authorities he went on leave, only to receive a summons from HM Customs for 'illegally imported a homing torpedo into Britain without paying duty', needless to say he passed the summons onto the Air Ministry.

He had been invovled in development of the Leigh Light from his early days at the CCDU and as a result he was tasked with carrying out its operational trials with No 1471 Flight, which was later absorbed by No 172 Squadron.

"GRESWELL, Jeaffreson Herbert, S/L (37318, Royal Air Force) - No.172 Squadron. This captain of aircraft has at all times displayed high qualities of perseverance and enthusiasm in the performance of his duties. On one occasion he carried out a successful low level bombing attack on an enemy submarine."
