it was different not just because it was a world war, but one that was modern yet still played out by some like a cricket match at Eton, bonkers riding into battle on the back of a horse, whilst being shot at by Germans with machine guns. They had cavalry as did the French, but the needless slaughter on all sides was what marks it out as so horrendous. General Jack Seeley is another hero, he rode his horse Warrior and led his troops throughout the war, surviving until old age, a remarkable man, story.
But much of it was slog, mud, sludge, bog, disease, mustard gas, and gory death. No glory in that at all.
