Hi Bigman,
1939-1945
1st Battalion- the original 1st battalion was captured at Singapore, so in June 1942 the 6th Battalion was reconstituted as the 1st Battalion and was placed under the command of the 53rd Division and served in NW Europe.
8th Battalion - was with BEF, then in Malta and then served with 10th Indian Division in Italy.
9th Battalion - was with BEF, then in Iceland and then served in 4th Indian Division in Italy before moving to 128 Brigade with 46th Division in Italy.
Hope this helps.
Bob B
