Polish submarines and Operation Worek

Operation Worek gives a concrete look at Polish submarine planning at the start of the Second World War. The boats were assigned defensive positions around Danzig Bay and the Hel Peninsula. Those positions kept them away from some enemy movements the Kriegsmarine expected them to attack. Wilk's attempted operations show the practical hazards: aircraft, anti-submarine vessels, depth-charge attacks, oil leaks, mistaken identity near Swedish waters, and the eventual order to head for Britain.
