The caption on the back of this photo reads "Arrived 20/9/17". The Unit War Diary says that on 19th September the Unit moved to BAVINGHOVE, and then by bus to Le Nieppe. On the 20th it says that "3 Motor Ambulances with 9 O.R. (other ranks) detached to 20 M.A.C.. Motor cyclist detached to 1st Aug Div. 1 O.R, evacuated sick." Reference to Harold Williams' B2455 shows that it was him that was evacuated, with what was later reported as scabies. Harold is in the above photo second from the right.
The date on the back of the photo doesn't accord with the unit diary, which says they arrived on the 19th, unless they are the nine detached to 20 M.A.C,, except that there are 10 of them in the above photo not nine. Unless they didn't count Harold who was evacuated.
On the whole they looked none too pleased about their change of accommodation, though Harold looks his usual chirpy self, despite being on the verge of being sent off with scabies.
I have created a number of local history projects for which you will find links on this blog. I am a community historian (ie, not paid) living in Essendon. The content of my Empire Called database (see the link to the PBWorks website) is the result of nearly 25 years' research. I began collecting material for the database of local WW1 volunteers in the early 1990s, beginning with hand transcriptions of Honour Boards in local schools, churches, clubs and so on. It was after this that the National Archives of Australia began making digitised service records available online, followed by the Australian War Memorial uploading Embarkation Rolls of the Australian Imperial Force. The Empire Called blog is a companion for the PBWorks website of the same name.
Time Travellers in Essendon and Flemington is set up in the same way, with a website and a blog to report additions to the website. The website is a vehicle to publish longer pieces of research that are too long for newsletters. It also includes various indexes I have worked on for many years, plus photos from various sources which I date and describe in greater detail. You may find something of use for your research.
