War Diary for New Zealand’s ‘blackest day’, 12 October 1917

On 12 October 1917, an offensive by New Zealanders at Passchendaele cost the lives of 845 men, and left more than 2700 wounded. In terms of lives lost on a single day, it was probably the greatest disaster in New Zealand’s history.


The image above shows a page from the October 1917 war diary for the New Zealand Division General Staff. The entry begins ‘Attack Day’ and goes on to outline what happened on what has since been described as New Zealand’s ‘blackest day’. The entire diary has been digitised and can be viewed online here:
