Thanks for sharing this article, Quasi.
The quote 'the line that stood between the British Empire and ruin was composed of tired, haggard and unshaven men, unwashed, plastered with mud, many in little more than rags' is like a mirror image of the verses of Wilfred Owen:
Bent double, like old beggars under sacks,
Knock-kneed, coughing like hags, we cursed through sludge,
Till on the haunting flares we turned our backs
And towards our distant rest began to trudge.
Men marched asleep. Many had lost their boots
But limped on, blood-shod. All went lame; all blind;
Drunk with fatigue; deaf even to the hoots
Of tired, outstripped Five-Nines that dropped behind.
I know that in France, a film has been made about the contribution of the soldiers coming for the French colonies during WWII
( film 'Days of glory'). I am not sure there is any film about their contribution during WWI!
