When/where did the cosmonauts fight wolves? or was it bears? With a gun? Could someone provide a more complete story?

One of comments on the article TidalWave linked in the Soyuz joysticks question had links to a pair of articles ^{1 2} on a gun that is a standard issue in the survival pack in all Soyuz capsules. The second article mentions the only non-training instance when the gun was used:

Every Soyuz spacecraft carries such a gun, although none of these guns have ever been unpacked in flight. And they have never been needed, with the exception of an incident in 1965, when bears (or wolves—the story varies) chased two far-off-course cosmonauts. The guns are often presented to crew members as postflight souvenirs. Although several survival kit bags have shown up at space auctions, I’ve never seen any of the guns for sale.

I tried to find more on that topic, but...

The first mission with a crew, Soyuz 1, launched on 23 April 1967 ^source

So either it was not Soyuz or the date is off.

Could someone provide the full story?
