In SH5 TwoS, the coastal defences are located in Hel peninsula, not in Danzig city.

Construction of a Polish Navy port at Hel, on the Peninsula's tip, began in 1931, and in 1936 the north section of the Hel Peninsula was officially declared the Hel Fortified Area (Helski Rejon Umocniony). Construction of the fortifications had not been finished before war broke out, but over several months as tensions between Poland and Germany had mounted, the fortifications had been reinforced with provisional earthworks.

The Fortified Area had coastal (anti-ship) and anti-aircraft artillery batteries. The Coastal Artillery Division [pl]'s coastal batteries comprised one battery of 4 152-mm (6.0-inch) guns, two older batteries of 2 105-mm (4.1-inch) guns, and three batteries of 8 75-mm (3.0-inch) guns. The 2nd Naval Anti-aircraft Artillery Division [pl]'s anti-aircraft batteries were equipped with 6 75-mm and 8 40-mm (1.6-inch) guns, 17 machine guns, and two 120-cm (47-inch) searchlights. Infantry cover for the Fortified Area was provided by a Border Defense Corps (KOP) unit – the Hel KOP Battalion [pl] under Major Jan Wiśniewski [pl] – which had several artillery pieces (4 75-mm, and 6 37-mm), 62 machine guns, and 2 large and 9 small mortars. The Coastal Artillery Division was 162 soldiers strong; the 2nd Naval Anti-aircraft Artillery Division, 1,000 soldiers strong; and the KOP battalion, 1,197 soldiers strong.

I never seen the Admiral Hipper in the Danzig Bay in the first mission. Always appears the Schleswig-Holstein and her two escorts (Z class destroyers).
