After the fire under the tree, what additional mishaps happen to the man?

The man's hands are so cold that he cannot light the matches and drops them in the snow.

The man lights the entire bunch of matches to start another fire, and although he hets the birch to light..... he also burns himself.

The man tries to grab the dog in order to kill it and burrow within the warmth of its body. He isn't succesful, thus, the dog gets away.

The man begins to run, hoping to restore his circulation, but his body isn't up to the task. He falls into the snow exhausted, where he falls asleep and soon dies.
