[1] After sea trials and working up in Holy Loch and Scapa Flow, Storm's first (and uneventful) patrol was to the Norwegian coast, north of the Arctic Circle.

This ended in failure when men in an inflatable dinghy sent out to retrieve the agent from the island heard him calling from the shore at night.

The fourth patrol was back to the Malacca Straits and a third victim was sunk by torpedo; this time the 3,000-ton Japanese auxiliary gunboat Eiko Maru.

The distance to the cruising grounds around Java and Celebes were so great that one of her ballast tanks was converted to carry diesel fuel in order to manage the 4,800-mile round trip.

In January 1945 Storm briefly held the record – 37 days – for a patrol by an S-class boat, covering 7,151 miles in the process.

[8] Before the war Storm's Captain, Edward Young, had been in publishing, and when he returned to the trade he described his wartime service in the book One Of Our Submarines (including his account of the loss of HMS Umpire (N82)).
