TODAY IN HISTORY - 12 OCTOBER 1917
One of the darkest days in New Zealand’s military history.
On 12 October 1917, New Zealand forces launched an attack at Passchendaele in Belgium. What followed was a devastating loss of life.
💔 More than 840 New Zealanders were killed within hours, with around 3,700 casualties throughout the day. It remains the highest number of New Zealand casualties suffered in a single day while serving overseas.
The battlefield had been transformed by relentless rain into a treacherous sea of mud. Men struggled to advance, supplies and equipment could not reach the front, and even evacuating the wounded became almost impossible.
In the aftermath, it took three days for stretcher-bearers to clear New Zealand casualties from the battlefield.
For those who survived, the loss of so many comrades left a lasting impact. Back home, communities and families were devastated by the news - with some families losing more than one loved one.
🕯️ 12 October 1917 remains a day of profound loss in New Zealand’s military history.
