After closing to a cable length of "Kattegat", Lieutenant Commander Seip hailed the German tanker, demanding that it identified itself. In response the German captain signalled that "Vidkun Quisling had been made the new prime minister of Norway and that all Norwegian naval vessels were under orders to cooperate with the German Kriegsmarine". Seip would receive no information from "Kattegat" before he himself had given his name and rank. While this signal exchange was going on "Kattegat" dispatched radio messages asking for "Kriegsmarine" assistance and escorting the remainder of the way to Narvik.
