Why Cumberland and carrier aircraft would trap Admiral Graf Spee

How much trouble would Admiral Graf Spee face against Ajax, Achilles, Exeter, Cumberland, and a Colossus-class light carrier?

The carrier would help hold her in place, while Cumberland and the other cruisers would provide enough force to finish the action.

Carrier aircraft could slow or damage Admiral Graf Spee enough to prevent a clean escape. That delay would let Cumberland join Ajax, Achilles, and Exeter. The German ship already faced a difficult cruiser pursuit without the extra heavy cruiser and air support. Combining both additions turns containment into a force capable of finishing the action.
