In June 1943 Donald, aged 20, came from the Intelligence Corps depot at Wentworth Woodhouse, near Rotherham to a course in Bedford where they studied Code Breaking at the Inter Service School there (ISSIS). At the end of the course Donald and one other, John Baynes, were selected to join JN 11 based in Bletchley Park. Here he spent the next two years from Oct 1943 working on Japanese Merchant Navy Auxiliary Codes.

A few documents have survived. Most notably there is an exchange of correspondence with the historian and author, Alan Stripp in 1995 where they discuss some of the organisation and personnel they encountered.

Donald had been asked to write and submitted a history of the JN 11 Unit in late 1945. This may well have survived and is probably held in the National Archives (HW 8/145)

Within Donald’s papers he kept, the VE day letter to all from Sir Stewart Menzies, Head of MI6 as well as the copy of a poem about Bletchley that is widely reproduced elsewhere.

We also have a collection of Bletchley Park programmes for a series of Reviews and Amateur Dramatic events. It is believed these were collected by Donald rather than by his future wife Pamela Downing, who was also working at Bletchley in Hut 6.

Although the married couple knew each other worked in Bletchley, they discussed none of their work in detail until after the mid 1970’s. Pamela worked in the high intensity environment of Hut 6 – where staff worked through the night, some times doing double shifts. The Japanese sections worked usually with pen and paper and only two shifts a day.

In Donald’s handwriting, recorded in 1995, there is a list of the following names, that represents some kind of organisational structure of Japanese Naval Section JN11 at Bletchley. Bletchley was notorious for its non hierarchical management, where civilians, ranking army officers and juniors worked together. Donald (DCM) held the rank of Warrant Officer in the Intelligence Corps.
