“Wolf!”

Lydia Angiyou's five-year-old nephew Paulussie whispered with alarm as he touched her

arm. At first, she didn't believe him.

Angiyou, Paulussie, her another newphew Lueassie, also five, and her youngest son Jessie,

seven, were walking to her mother's house one night last February. Animals were often sighted

near lvujvik--a village of 274 Inuit on the shore of Hudson Bay--but rarely on its streets.

The 41-year-old teacher and mother of five turned around. Looking behind her into the

darkness, at first she thought that Jessie was the wolf. But a meter behind the boy was 350kg

polar bern -no wolf in sight--standing on the icy road. Jessie turned and saw it, too, then ran,

screaming, to his mother.

Angiyou felt a rush of blood to her brain. "Get as far away as you can!" she shouted to the

boys as she ran towards the bear. She stopped just in front of it, then faced it quiedy. It made a

move to go around her to get to the boys, who must have seemed like the easier meal.

But Angiyou moved with the bear to maintain her position blocking the children. Finally she

got the animal's attention. In response, it rose on its hind legs to its full 2.5m height. The bear

charged, and knocked her into a seated position. The skin under her nose tore. Falling onto her

back, she screamed for help and kicked at the animal in a bicycling motion. She soon passed out.

Sirqualuk Ainalik, a fellow teacher, had been at his brother's house nearby when Jessie

dashed inside for help. Grabing a rifle, the 33-year-old ran to the road, firing a warning shot into

the air. He then aimed his gun at the huge bear.

With two more shots, Ainalik killed the polar bear.
