[edit] Before the battle

Gdynia is a major civilian and military port on the Baltic Sea, and was an important industrial centre of the Second Polish Republic. Its defence was one of the key elements in the Polish defence plan. One of the Polish armies, Armia Pomorze, had orders to prevent German forces from breaking through the Polish Corridor that linking most of Germany with Prussia and to defend Gdynia, Hel, Kępa Oksywska and Oksywie.

The forces defending Gdynia were grouped under the Land Coastal Defence (Lądowa Obrona Wybrzeża), commanded by Colonel Stanisław Dąbek and Naval Coastal Defence (Morska Obrona Wybrzeża) Captain Stanisław Frankowski. The Polish plan foresaw that the Germans would manage to cut off Gdynia from the main forces of Armia Pomorze; therefore, the Land Coastal Defence was tasked with defence of the coast for 8-10 and promised reinforcements after that period. It was thus prepared for individual operations and reassigned from Armia Pomorze to the Polish Navy, and Stanisław Dąbek received orders directly from counter-admiral Józef Unrug. The Polish Navy would support the coastal defence with 1 destroyer (ORP Wicher; 3 other destroyers had been evacuated from the Baltic Sea during Plan Peking), 1 heavy minelayer (ORP Gryf) and several submarines and smaller surface ships.

On 1 September, the Polish Land Coastal Defence force had a strength of approximately 17,000 (increased from about 5,000 two months earlier), with 40 artillery pieces (including 8 anti-aircraft), 34 mortars and granade launchers and approximately 400 machine guns. Infantry units were placed:

west and Wejherowo:
south of Gdynia, at Redłowo
at Kartuzy
at Koleczkowo
at Gdynia and Kępa Oksywska

The German forces tasked with the capture of Gdynia were commanded by General Leonard von Kaupisch and formed part of the Army Group North under General Fedor von Bock. They were approximately 29,000 strong, with over 300 artillery pieces, 70 mortars and grenade launchers and 700 machine guns. The German Navy (Kriegsmarine) in the area consisted of 2 old battleships, 3 cruisers, 10 destroyers and several smaller units. Approximately 120 Luftwaffe planes were supporting the German forces.

[edit] The battle

The German offensive isolated the Polish coast from the Polish mainland between 4 and 8 September, and Armia Pomorze was forced to retreat south-east. Units of Land Coastal Defence has been engaged by the German forces from 1 September, although it was not until the second week of the war that the Germans would begin a direct assault on the Polish port of Gdynia.

The German Navy, operating in the area with the pre-dreadnought Schleswig-Holstein and smaller units shelled Polish positions, but with limited effect and prevented from closing on the coast by Polish coastal batteries.

The German land offensive was much more successful. German forces established a connection between Germany and Prussia by 4 September. After heavy fighting near Kartuzy (5 September), their main attack towards Gdynia began on 8 September, and after intense fighting near Puck and Wejherowo (8 September) step by step the Poles were forced back towards the sea.

When the Polish positions outside Gdynia were overrun, and in view of the retreat of the Armia Pomorze, on 10 September Colonel Dąbek decided to abandon Gdynia in order to avoid civilian casualties during the city fighting, and thus on 12 September he ordered all Polish units to retreat from Gdynia toward Kępa Oksywska, a fragment of the coast near Puck Bay. On 11 and 12 September the fights near Mechlinki transformed into an incessant two-day battle, after which Polish troops had to retreat again.

The Germans captured Gdynia on 14 September. Kępa Oksywska was not prepared for siege or provisioned for the approximately 9,000 strong remaining Polish forces and in the battle of Kępa Oksywska the Poles sustained heavy losses (approximately 2,000). After a last failed counterattack on 19 September, Colonel Dąbek, who participated in the frontline battle and was wounded, decided to issue order to surrender and committed suicide after giving the order to cease fire.

The Polish Navy was tasked to provide support to Gdynia through Plan Worek (submarine operations) and Operation Rurka (mining sea approaches). These plans did not prevent defeat.

Polish soldiers fought gallantly, and they did not spare blood. The area of Gdynia and Danzig was defended by the elite of the Polish armed forces. Those were young and inspired units of the navy and army, which fought admirably. On the plateau of Oxhöft we found trenches filled with dead Polish soldiers, who fell by hundreds where they fought, with the rifles still in their hands. It was apparent, that they fought to the bitter end. from F. O. Busch, Unsere Kriegsmarine im Polnischen Feldzug[1]
