A reserve HMS Tiger could transform the River Plate pursuit

The discussion moves from escort numbers to the effect of retaining a fast capital ship such as HMS Tiger. In this counterfactual, Tiger joins Harwood's Ajax, Achilles, and Exeter at the River Plate, leaving Admiral Graf Spee little prospect of escaping intact. A decisive sinking would remove the need to send Renown and Ark Royal south in pursuit. Those ships could then serve elsewhere, demonstrating how one reserve hull can alter several later allocations rather than only the battle it joins.
