hiya gerry
i agree you have a bit of a mystery here,his medal roll entries say he landed in egypt on 28-9-14,which means he sailed with the battalion on the 10-9-14,this must surely be a admin error because he didnt enlist until 22-3-15.
regarding the soudan entry in his paybook
this is just a small summary about the soudan around the dates given in his paybook
the hospital ship soudan was at suvla bay in august,she took on board hundreds of sick and wounded and sailed for mudros,at 7am on 24th august,she sailed from mudros for england and arrived at devonport on 3rd september,its possible the soudan reference was crossed out because he wasnt aboard the soudan when he was paid on 10th september,all the patients would have been disembarked within 24hrs
on 7th october she sailed from gallipoli and arrived at malta on 13th october
