At dawn on 9th April I sang during a ceremony to commemorate the Battle of Arras. We gathered outside the Wellington Tunnels. Around twenty metres below us was a network of tunnels, which was expanded by largely Māori soldiers from the New Zealand tunnellers. Some of the tunnels are open for visitors today. Over 24,000 allied soldiers and officers sheltered there in 1917 before pouring out at dawn on 9th April in a surprise attack. The battle claimed over 250,000 casualties.

As the ceremony drew to a close, the sun rose and we heard birdsong and the gentle hum of Arras’s morning traffic. A peaceful contrast to the pandemonium and death of 107 years ago.
