Ninety-nine years ago New Zealand suffered an agonising military defeat. In the space of a few hours, on a sodden Belgium battlefield, hundreds of young New Zealand soldiers died on what remains the worst day in the nation's military history.
The New Zealand Division made two attacks as part of the British plan to capture Passchendaele ridge on the Western Front.
The actions were wrapped into a series of strikes in the Third Ypres, a big Allied offensive which lasted from July until November in 1917 and covered in all eight separate battles. It was one of the bloodiest assaults of World War I.
The first advance on October 4 in the Battle of Broodseinde succeeded, though it came at a cost, with 330 fatalities and hundreds more wounded. Despite this heavy toll, the battleground objectives were secured, and the frontline pushed over 2km into enemy territory.
The second advance, the First Battle of Passchendaele on October 12, was a catastrophe.
