What does the evidence suggest sank HMS Hampshire?
Short answerA German mine is the best-supported explanation, and the case illustrates how effective mine warfare could be against ships and convoys.
NotesA mine is the best explanation for HMS Hampshire because it matches both British and German evidence. A related example sketches a paired submarine tactic: one boat trails and reports a convoy while another lays mines ahead of it. That approach could force escorts to confront an obstacle field without requiring the large wolf packs needed to overwhelm a convoy directly.
