Thanks for getting in touch.
Your father served overseas with both 1/23rd London and 2/23rd London. Not too many men in the regiment did that.
From the records it looks like he joins 1/23rd in France in 1915 and remains with them until he's wounded at High Wood on the 16th September, the same day my grandfather was wounded. Wonder if they knew of each other? Then transfers to 3/21st while he's recuperating from his wounded ankle in UK. When he's fit again in Jan 1917 he's sent out in a draft to 2/23rd in Salonika, and stays with them through all their time there and in Egypt. He returns to the Western Front when 2/23rd are transferred to 30th Division and service just south of Dunkirk on the French-Belgian border. His final wounding isn't mentioned in the war diary, but it looks like they were moving up to the front line, so perhaps a sniper caused it.
For now your best bets are the war diaries: http://qrrarchive.we...u2.aspx?reg=ESR
and the official history http://www.naval-mil...1798-1919..html
., and there are some bits on 16th September in this thread or elsewhere on the forum.
The illegible name that you mention for 30/06/18 is Taranto. They sailed the Med to Italy and then went by train through Italy to Northern France. 2/23rd certainly got to see quite a bit of Europe and the Middle East compared to the experience of 1/23rd.
Incidentally, did you get the additional pages from his service record? Not much on them but worth having. The Ancestry Indexing puts you about three pages into his complete file when you type in his name and the preceeding pages are also part of his file. It's slightly annoying that a couple of sheets you often find in the service papers haven't survived for him, namely those that record every little detail about his movements and would show which Casualty Clearing Station he was sent to after his woundings and his route home after each, but at least you have the bulk of his file.
Do you happen to have any photos of him you could share with me on here or via pm? I have a special interest in those 16th September men.
