The German squadron including the Tirpitz turned back from intercepting convoy PQ 17 partly because the convoy had effectively ceased to exist as a unified entity.
Notes on verification
Multiple independent sources confirm the German squadron was recalled partly due to the convoy's dispersal removing the rationale for engagement, though most emphasize detection risk by Allied submarines/aircraft as the more immediate trigger. The scattering is best framed as a contributing factor rather than the primary cause.
