The Lighthorsemen
If you enjoyed this film you should look out for the mini series entitled "ANZACS" which was made as a Television Mini series about the same time as The Lighthorsemen.
It follows a group of Aussies from the early days of 1914 to Gallipoli to the battle of the Somme, Paschendaele, Ypres, and the final battles of 1918 to the Aussies returning home in 1918 and 1919.
Well worth viewing, available in VHS and DVD from Australia.
A great series which also stars Jon Blake.
Hope you enjoy,
