That's great Charlie,
9th Lancs Fusils lost 125 men on the Somme on 26/09/1916, including most officers and none of their other Bttns had casualties. Sadly the War Diary doesn't mention the officer casualty list, so we can't verify if Walters was there.
Tim
ps 34 Bgd War Diary doesn't name the officers either and I can't find any reference to 2/Lt Walters in earlier sections of either diary.
pps The Newcastle Journal of 05/10/1916 states 2/Lt Walters was attd to OBLI. I'll report back...
pps 6th OBLI was their only Bttn with losses on 26/09/1916. No names in Bttn or Bgd War Diary.
