What policy did Germany adopt to sink Allied shipping without regard to engagements?

• A. Naval blockade
• B. Wolf Pack doctrine
• C. Unrestricted submarine warfare
• D. Siege warfare

Answer: (C)

Unrestricted submarine warfare is the policy where submarines target and sink ships, including merchant vessels and neutrals, without warning or regard to usual engagements or prize rules. This approach aimed to choke off Allied shipping by striking first and broad, rather than stopping ships to inspect them or distinguish combatants from civilians. It’s the clearest fit for describing a policy that would sink Allied shipping without regard to engagements or warnings.

The other ideas describe different naval concepts: a blockade is about cutting off a nation's access by sea, not a unilateral practice of sinking without warning; a wolf pack is a tactic where submarines hunt in coordinated groups, not a policy of disregarding engagements; siege warfare is a land-based method for capturing a place by surrounding and starving it, not naval shipping policies.
