The best modern history of a single battalion I have read is McCrae's Battalion about the 16th Royal Scots, the 2nd Edinburgh City Bn, who were part of 34th Div on the first day of the Somme. It is a WW1 Band of Brothers and the sporting aspect of it, many members being from the Hearts football club and it's supporters does not detract - if you have no soccer interest per se - from a fantastic and very sad story. I think it should make a film/tv series - but there are no yanks involved. If anything, the 34th Div; Tyneside Scots and Irish, two Edinburgh bns, Cambridge men (Suffolk Regt) and the Lincolns could almost be a WW1 version of the much hyped and loved 101st AB. But they're only of interest to the WW1 crowd.
