 The plan was created for the five Polish submarines "Orzeł" (Eagle), "Wilk" (Wolf), "Sęp" (Vulture), "Żbik" (Wild Cat) and "Ryś" (Lynx) to use, in the event superior enemy surface forces took control of the Baltic Sea (the Polish surface navy consisted only of four destroyers, some minelayers, minesweepers, and gunboats).The submarines were to operate near the Polish coast, in the area of the Danzig Bay and the Hel Peninsula.They were to conserve their limited munitions for "significant military targets" (destroyer or larger) shelling the Polish coast or attempting to land forces on it and interdict naval traffic between the German mainland and East Prussia.
