How the Royal Navy might have fought around Guadalcanal

How would the Royal Navy and British forces have performed around Guadalcanal?

Probably comparably to the Americans overall, with aggressive cruiser-destroyer tactics at sea and outcomes still heavily dependent on who controlled the engagement.

At sea, Tribal- and L-class destroyers and Arethusa-class cruisers would likely lead aggressive surface actions, informed by hard-won wartime experience. On land, British, Australian, and Gurkha forces would probably perform broadly like the US Marines rather than transform the campaign by themselves. A later follow-up cites British motorization, artillery spotting, tank integration, and North African experience as reasons a differently organized force could still deliver broadly equivalent combat power. The central qualification is command: British forces did well when they controlled the pace, but could struggle when the enemy seized the initiative.
