You have almost certainly heard of War Horse, Michael Morpurgo's 1982 novel about a farm horse bought by the British Army to serve in WWI. It was later adapted into an award-winning play (which I can highly recommend, though take a box of hankies with you) and later still a film adaptation directed by Steven Spielberg.
There is also a war horse in my own family. My ggg-uncle was John Birrell Horsburgh (1865-1940) and his eldest son was John Harvie Horsburgh. John was born on Forfar Road in Dundee in 1892 and, as a teenager, worked in a jute mill. By the time of the Great War he was working as a cab driver and served in the war with the Royal Engineers. After being demobbed he worked as a carter (something of a Horsburgh family specialty) for contractor James Wilson of Malcolm Street, Dundee.
Also starting at James Wilson's, in 1918, was an 11-year-old horse called Darkie. Darkie, so-called because of his handsome black coat, had crossed the Atlantic to Britain in the early years of the war with a French-Canadian Battalion and had gone with them into battle-torn France where he sustained seven injuries to his fore-end, flanks and legs. When the war was over he was bought by Wilson's and was soon teamed up with a carter, my cousin John Horsburgh.

In about 1928 both John and Darkie moved to Tough Brothers, merchants and manufacturers at the Anchor Works in Anchor Lane. Darkie was a 'Belgian type' but had the short neck and powerful shoulders of a Clydesdale. He was an intelligent creature, able to position himself correctly depending on whether he was pulling a cart or a lorry, behaving better than many motorists at traffic lights, able to shift himself out the way of a passing bus upon hearing its horn, and he knew his way round the twists and turns of the Corporation gasworks yard without the slightest guidance needed.
In 1933 Darkie took part in the Broughty Ferry Carnival, and in 1935 he was spruced up and decorated for King George V's silver jubilee. But in August 1937, having never needed to see a vet in all his carting career, he died of an internal ailment. He was about 30 years old and had been at work just the day before. John Horsburgh was inconsolable ...
"... aye, [he was] as cheery at the end o' the week as he wis at the beginnin'. He wis the maist wice-like horse I've ever had onything tae dae wi'."
John himself had married in 1916, to a jute spinner, Elizabeth Anne Williamson. They had five sons (that I know of), though both parents would outlive two of them (James died aged 1 in 1922 and William died aged 25 in 1945). Elizabeth died in 1968, age 73, and John died age 76 in March 1969, just three months before my own birth.
