HMS Unbroken navigates a minefield

HMS GRAPH (ex U-Boat U 570) at Holy Loch on the completion of a trial trip, passing by a depot ship. In the foreground are the conning towers of HMS STURGEON (left) and HMS TIGRIS whilst submarine P 42 (later renamed HMS UNBROKEN) can be seen in the background.

Inside the minefield I had the mine-detecting unit – a refinement of the Asdic – switched on in an effort to plot the pattern of the mines and sail between them. A regrettable action. We plotted mines right enough-ahead, to starboard, to port, above, below – everywhere! Cryer’s eyes popped from his head as he reported each new echo, and a few wild expressions and quivering lips were to be seen in the control-room.
