A hundred years later, his great-great niece Jodie Tisdall, of Middlemarch, will call the ''roll of honour'' at the Strath Taieri and Deep Stream Soldiers' Memorial in Middlemarch on Anzac Day, this Saturday.
The names of the fallen soldiers called will include Private Peat.
Before Pte Peat joined the Otago Infantry Battalion, he was working on the family's sheep and beef farm at Sutton, Mrs Tisdall said.
Pte Peat was killed in action at Gallipoli, on August 7, 1915, two days before his 20th birthday.
Pte Peat's name was etched on the Middlemarch memorial and the Chunuk Bair Memorial at a cemetery on the Gallipoli Peninsula.
Pte Peat was one of four brothers, all sheep and beef farmers in the district, who all served in World War 1.
His eldest brother, George Peat, Mrs Tisdall's great-grandfather, made it home and received a medal for acts of bravery in France.
He and another soldier stopped the enemy from advancing by moving a gun to a flank.
''In the attack, 10 men were killed and 22 were wounded, but it would have been worse if they hadn't done what they had.''
The other brothers, Jack and David, also returned home and more Peats were listed on the Middlemarch memorial after serving in World War 2, she said.
On Saturday, Strath Taieri School pupils - including Mrs Tisdall's son William (8) - would hold the picture of 22 of the district's fallen soldiers.
''We want to put faces to names, because a lot of people have no idea,'' Mrs Tisdall said.
