I went straight to scappa flow first chance I got and sank two cap ships, getting in there decks awash was a lot of fun dodging patrols. Had a bit of a das boot moment when they spotted me; on the bridge alone (crew bugger off if you are decks awash) full ahead dodging gunfire, felt like yelling at Thompson to go "faster dam it, faster"
was awarded a VIIc and an iron cross as soon as I got back. Feels a bit cheap having gotten it straight away, not to mention impossible historically, will avoid scappa flow until told to next campaign.
