"So... Hastings said 80% of soldiers returned. Paxman said 90%.

Which one are you going to shout Liar! at Keith?" - asks Musket

Of course the answer is neither as one has "rounded up" and the other has "rounded down". It also depends upon who and what precisely they are talking about.

Those in the British Army? Commonwealth troops? Empire troops?

Total numbers are:
5,704,416 British troops
7,165,280 British, Dominions and Commonwealth troops
8,689,467 British, Dominion, Empire and Commonwealth troops

What location were they talking about?
Every location and theatre of war?
Western Front?
Mesopotamia?
Egypt and Palestine?
Salonika?
Italy?
Gallipoli?
Others?

But roughly overall with regard to the First World War 7,165,280 served in the British, Commonwealth, Dominion and Empire Forces during the First World War of which 956,703 were killed so 86.6% came back

By the way Christmas, what claims were abandoned half a century ago? The only people I see here peddling myths, half-truths and misrepresentations have been yourself and Musket - I can detail them all if you wish, but I don't think I'll bother, because as Dave the Gnome says it would not make the slightest difference to you regardless of what evidence was ever presented to you such is your biased bigotry - If you wish to fool yourself and continue to believe and repeat lies in any discussion then you can fully expect to be continually pulled up on them.

While Keith and myself have produced facts, details, sources based upon historical events, analyses and research, you have relied on cherry-picked personal opinions, essays and poems. But there again the inability of the likes of yourself and Musket to actually read and understand the subject matter has to be taken into account.
