What struck them on January 2?
Or
How did the first ‘disaster’ strike the ship?
On New Year’s Day the weather changed for the worse. The waves were gigantic. Strong gales did trouble them. As the ship rose to the top of each wave, they could see endless huge waves rolling towards them. The howling of the wind and the spray was painful to the ears. The sky grew dark. A torrent of green and white water broke over the ship. The captain was thrown overboard.
