The Worek Plan assigned Polish submarines to defend the Danzig and Hel area through torpedo attacks and mine-laying. They operated without supporting forces, and the loss of their bases would trigger withdrawal to Britain or, if necessary, a neutral port. Wilk's mine-laying capability made it especially suited to creating obstacles in the defended waters. It laid mines on 3 September but suffered depth-charge attacks and recurring technical problems while attempting further attacks. Three Polish submarines ultimately went to Sweden, while Wilk and Orzeł escaped to Britain. Wilk passed through the Danish straits and arrived on 20 September.

Wilk loses shore support during Poland's submarine defence
Wilk lays mines under the Polish defensive plan, then escapes after depth-charge attacks, technical failures and the loss of naval bases.
