After being released from a Siberian labor camp during the Nazi invasion of Russia in 1942, the 22nd Polish Supply Brigade began a long trek south toward Persia. Along the way, they bought an orphaned bear.
"He was like a child, like a small dog. He was given milk from a bottle, like a baby. So therefore he felt that these soldiers are nearly his parents, and therefore he trusted in us and was very friendly," Wojciech Narebski, former Polish soldier, told the BBC.
As he grew, his diet changed, but he remained friendly.
The bear became fond of drinking beer, as well as smoking, and even eating cigarettes. "For him one bottle was nothing, he was weighing 440 pounds. He didn't get drunk," Narebski said.

The company was fond of boxing and wrestling with Wojtek, as seen in this footage.
While he was still small enough, Wojtek would hang out of the passenger side of trucks, until he eventually grew so large he had to be transported in the back of cargo vehicles.
By 1943, the Polish company had reached Egypt and was preparing to reenter the war zone in Italy. The army had strict rules denying pets passage to war zones, so the company did the only thing they could — they made Wojtek an official soldier.
Because of his fearsome size and strength, Wojtek carried crates of munitions much easier than his human comrades. He inspired the emblem for his company.
