hi carole
the 5th battalion was a territorial unit based in Wigan, formed from local men, they were created to provide defense for the UK homeland
on the outbreak of war in 1914, the territorial battalions were asked to give up their uk duties and fight abroad with the regular army. generally speaking most accepted. these battalions (5th, 6th, 7th, 8th and 9th edit 'and 10th') became part of the 42nd (East Lancs) division and went off to gallipoli via egypt.
the men who stayed behind formed the basis of a new battalion which was designated 2nd/5th ( the original battalion was now known as the 1st/5th.) their main purpose of the 2nd/5th was to train and supply replacements to 1st.
later on in the war, after conscription, the 2nd/5th went to war in it's own right and a third battalion was raised, this being the 3rd/5th. this was then the reserve battalion to the other two and as such did not leave the UK
i hope this makes sense
