If enough people latch onto the polar bear from behind, and a few others grab each leg to restrain it, the sheer weight and strength of the group should be able to slow its movements considerably. Polar bears are not immune to being overwhelmed by coordinated force when they are partially restrained, and the human side have 200 men at their disposal here.
From there, the others could gouge the polar bear's eyes out and begin dealing damage, as long as the men are strong enough to breach its natural defenses (thick fur, dense muscle). Extremely dangerous because this strategy is 100% going to result in the deaths of the first ten-something men here, but with sufficient numbers and proper coordination, this strategy should theoretically work?
