The German surrender lists are dominated by Type VIIs and other home-fleet boats, while Norwegian ports show a more operational mix. Type XXI and Type XXIII concentrations around Horten and Kristiansand look like boats escaping Germany, while Type VII groups at Trondheim and Narvik more plausibly represent operational boats returning from the Atlantic. Stavanger and Bergen help show the transition between those patterns. Geography becomes evidence for the fleet's final movements rather than a simple list of hulls.
