Significance

Operation Source targeted the concentration of German capital ships — Tirpitz, Scharnhorst, and Lützow — based in northern Norway. These vessels posed a persistent threat to Allied convoys running to the Soviet Union and tied down substantial British naval resources as a containment measure. Neutralizing or disabling them would relieve pressure on convoy escort planning and free surface units for other theaters. The operation reflected British commitment to removing the 'fleet in being' threat that German heavy ships represented in Norwegian fjords without risking a surface engagement.

Tactics

The operation was carried out using X-class midget submarines, which were employed to attack the German warships in their Norwegian anchorages. Beyond the use of these specialized craft, the supplied overview does not describe the specific maneuvers, dispositions, or tactical execution of the attacks.
