Lewis was contacted by the Ministry of Information as a potential artist, but as he was already working for the Canadian War Records, his appointment had to be delayed. The chosen subject was Heavy Artillery, due to Lewis's service in this area. Lewis was also ill for several months with flu, which prevented him working. By October 1919, the picture had still not been completed but it was finally acquired that December (IWM:ART 2747). In the meantime, a work had been purchased for the Museum by Muirhead Bone (IWM:ART 1672) - for details see Bone fund file (Old Ref 39/2 ).
The file includes correspondence regarding expenses, and loans of works; three works by Lewis, included in the Ministry's exhibition to America in 1919, which were then retained in storage at the Museum; and conservation of IWM:ART 2747 following damage in an air-raid during the Second World War.
