The British attack on the 9th at Ypres was an unfortunate failure, with virtually no ground taken. This somehow appears not to have been understood by senior commanders, with Plumer (the local commander) telling Haig (the British Western Front commander) that good positions were taken from which to advance on Passchendaele. Now the next attack takes place, an attempt mostly by Australian and New Zealand troops to take this ruined village.
The attack is a failure. Mud and the German defenders prevent any major gains; at the end of the day’s fighting the New Zealanders are roughly 90 metres closer to the village and have taken terrible casualties in the process. German losses are great too, thanks to Allied artillery and German counterattacks to recover lost positions. But although he is shaken by the scale of losses his men have been enduring, Ludendorff is now increasingly confident that the line can be held until the weather becomes so bad that further offensives are impossible.
