Describe the trouble that manage Peter and Patel leave Russia?

Peter and Pavel were driving a sledge with the bride and groom on it. Wolves started to attack all of the other sledges behind them that included the rest of the wedding party. Peter and Pavel tried to get the groom to push the bride out so that they could escape, but he refused. They then pushed them both out and ended up being the only survivors. At that time, they were pariahs in their town, so they left and came to America.
