team 4 had charges to place on twelve crude oil tanks and they began to place them as soon as team 1 gave the order to start. about seven minutes after they started, one of their charges prematurely exploded and they decided to place the remaining charges together and captain de kok armed one but it exploded and the other two team members of the team were injured. one badly team member made it back to the entry point and so team 1 and 2 re-entered the refinery to find the two missing men and found another team member badly burnt and blinded and returned him to the entry point and resumed their search for the de kok, but after a third premature explosion it became too dangerous and it was realised he could not have survived.
