The officer saved Paul and commanded all to go to the shore, so they did that.

Acts 27:42-44

42 The soldiers said to one another, “Let’s kill all the prisoners on the ship, so that they will not be able to swim away and escape.” They planned to do that because they were sure that officials would order them to be executed if they let the prisoners escape. 43 But Julius, the army captain, wanted to save Paul, so he stopped the soldiers from doing what they planned to do. Instead, he commanded first that everyone who could swim should jump into the water and swim to land. 44 Then he told the others to hold onto planks or pieces from the ship and go towards shore. We(exc) did what he said, and in that way all of us arrived safely on land.
