Twenty metres under the streets of the French town Arras, 24,000 World War I soldiers sheltered in a 19-kilometre network of tunnels and prepared for battle.
At their most complete, the tunnels had running water, electric lights, kitchens, a light rail system and a fully equipped hospital, thanks to the efforts of 43 members of the Māori Pioneer Battalion, who dug the tunnels alongside many others.
The battalion, and hundreds of soldiers from the New Zealand Tunnelling Company, spent years turning the 200-year-old abandoned quarry into a life-saving underground shelter, working in the dark with the constant threat of carbon monoxide poisoning and tunnel collapse.
To help tunnellers navigate underground, the caverns were given the names of New Zealand cities: Wellington, New Plymouth, Christchurch and Dunedin. The soldiers also carved names and messages into the tunnel walls that can still be read by visitors.
A delegation from Arras honoured the descendants of that battalion at a ceremony at Te Papaiouru Marae in Ōhinemutu on Tuesday.
Arras Mayor Frédéric Leturque said it was a privilege to be in Rotorua for the commemorations.
“This is a day which makes a lot of sense for me as mayor of Arras and for all the people of Arras and France, because the Māori Pioneer Battalion members played a strategic role in World War I,” Leturque told the Rotorua Daily Post.
“They crossed the sea, arrived in France, dug the tunnels and, in doing so, they allowed thousands of soldiers to be protected.”
Walker said his ancestor’s experiences taught Walker and his sons the meaning of strength.
“Don’t give up. Kia kaha - stay strong, even when you feel weak.”
Eleven-year-old Iraia Kennedy Tuari travelled from Gisborne to “be there for his tūpuna”.
“For me, today is about representing,” Iraia said.
Iraia said he was surprised at the ceremony to discover he was related to more members of the tunnelling battalion than his great, great grandfather Toi Karini.
