Jagger wrote to the Ministry of Information enquiring about official war art work. He was also recommended by John Singer Sargent. He was released to the MoI by the military authorities and it was planned that he should work on the scheme for the Memorial Hall, although this was later abandoned. However it did lead to the acquisition of IWM:ART 2287.
The file includes a b/w photograph entitled 'The Listening Post' (actually 'No Man's Land'). Other correspondence concerns Jagger's requests for access to military equipment as source material for his works; various schemes to arrange the acquisition of IWM:ART 4952-3 and 4956-7, all the gift of Jagger's widow in 1936, and IWM:ART 5003, purchased in the same year; and conservation issues relating to Jagger's works in the collection.
