The Battle of the Somme

Yes some of these scenes were "Re-Enacted" for Propaganda/Enlistment purposes but let's not forget that every single soldier in this Movie, Documentary call it what you will are now dead, Most probably died at that time in that place or in later battles. Much footage was cut from the public version, as the War Office wanted the film to contain images that would support the war effort and raise morale.

It still manages to portray the horrors of war and its utter futility, did we learn our lesson

No,no we didn't

This is a remarkable piece of Cinema that has now passed from living memory

Lest We Forget
