In their book Gresley's Silver Link' the authors analysed the evolution of the A4s Gresley's and their service up to Gresley's death in 1941\. This book takes this compelling story from the early years of the war up to their demise in the 1960s After four years of service pulling the LNER's most prestigious trains the A4s took on a more utilitarian role and for six years worked hard to support Britain's war effort. From this they emerged bowed, but unbeaten, although in an extremely jaded condition. Once restored they took up where they had left off in 1939 and did exceptional service for the rest of their days. With the help of previously unpublished material the authors analyse the second phase of the A4s careers, first as LNER engines, then, from 1948, under British Railways management. Without a diesel or electric fleet of engines to replace them they entered a second golden age of fast running in the 50s. Then in the Swinging Sixties' they faced, as some thought, a premature end as part of a much delayed modernisation programme. Until withdrawn from service they continued to astound their footplate crew and performed exceptionally well, even when maintenance standards had slipped and their condition had deteriorated. They were thoroughbreds and have become a fitting memorial to the master engineers who produced and sustained them for 30 years or more.

He landed in France on D Day plus 2, then, after a short period in hospital, returned to the battlefield to be involved in the drive across Europe to Germany. He was in the forward units that discovered Bergen-Belsen and returned a few weeks later to help burn it down with a flame thrower equipped Bren Gun Carrier.
