When Polish forces were deployed to Europe the only way to take the bear with them was to "enlist" him.
So he was given a name, rank and number and took part in the Italian campaign.
He saw action at Monte Cassino before being billeted - along with about 3,000 other Polish troops - at the army camp in the Scottish Borders.
The soldiers who were stationed with him say that he was easy to get along with.
"He was just like a dog - nobody was scared of him," said Polish veteran Augustyn Karolewski, who still lives near the site of the camp.
"He liked a cigarette, he liked a bottle of beer - he drank a bottle of beer like any man."
When the troops were demobilised, Voytek spent his last days at Edinburgh Zoo.
Mr Karolewski went back to see him on a couple of occasions and found he still responded to the Polish language.
"I went to Edinburgh Zoo once or twice when Voytek was there," he said.
"And as soon as I mentioned his name he would sit on his backside and shake his head wanting a cigarette.
"It wasn't easy to throw a cigarette to him - all the attempts I made until he eventually got one."
Voytek was a major attraction at the zoo until his death in 1963.
Eyemouth High School teacher Garry Paulin is now writing a new book, telling the bear's remarkable story.
'Totally amazing'
Local campaigner Aileen Orr would like to see a memorial created at Holyrood to the bear she says was part of both the community and the area's history.
She first heard about Voytek as a child from her grandfather, who served with the King's Own Scottish Borderers.
"I thought he had made it up to be quite honest but it was only when I got married and came here that I knew in fact he was here, Voytek was here," she said.
"When I heard from the community that so few people knew about him I began to actually research the facts.
"It is just amazing, the story is totally amazing."
