I remember watching the 1981 movie Gallipoli – it focuses on a couple soldiers leading up to the campaign, it’s pretty depressing (as WWI movies tend to be) but pretty good.

Cohen’s “Military Misfortunes” has a chapter on how badly the Suvla Bay landings were handled. To be fair, amphibious landings are challenging.

Wait, I think I also read a case study on how well the final withdrawal was done. I think it was in Barton Whaley’s “Stratagem”. As I recall, they withdrew everyone and even all heavy equipment without the Ottoman soldiers noticing, leaving behind only one pack animal that refused to budge.
