It seems that the phenomenon of those Flanders poppies about which Canadian poet, artist, doctor and artilleryman Colonel John McCrae wrote has been evident after every battle in the area.
The British historian Lord Macaulay wrote in 1855 about the site of the Battle of Landen in the Province of Brabant. The battle took place in 1693, during the Nine Years War between the French and the English when William III was on the throne. Landen is in Belgium and is approximately one hundred miles from Ypres. The French lost 9,000 men and the English 19,000:
"The next summer the soil, fertilised by twenty thousand corpses, broke forth into millions of poppies. The traveller who, on the road from Saint Tron to Tirlemont, saw that vast sheet of rich scarlet spreading from Landen to Neerwinden, could hardly help fancying that the figurative prediction of the Hebrew Prophet was literally accomplished, that the earth was disclosing her blood, and refusing to cover the slain."
