 Lt <unk> Newman aboard the MGB , need not have landed , but he was one of the first ashore . One of his first actions was to direct mortar fire onto a gun position on top of the submarine pens that was causing heavy casualties among the Commandos . He next directed machine @-@ gun fire onto an armed trawler , which was forced to withdraw upriver . Newman organised a defence that succeeded in keeping the increasing numbers of German reinforcements at bay until the demolition parties had completed their tasks .
