British global-war preparation overmatched an improvised Italian posture

A convoy protected by the cruiser Leander and destroyers carried more firepower than the flotilla could safely challenge. Britain had spent the interwar years preparing for attacks on global trade and expected its dispersed escorts to face locally superior raiders. Italy assembled its East African posture after imperial expansion and had ideas and infrastructure without the ships and stores required for a mature system. Tankers, water carriers, the minelayer Ostia, and the auxiliary cruisers Ramb I and Ramb II added useful capabilities but could not replace that missing support depth. Ostia was lost to a Royal Air Force attack, while Ramb I's encounter with Leander ended badly for the Italian raider. The German commerce raider Pinguin entered the region expecting Italian support, found that the flotilla lacked enough stores for itself, and eventually encountered the County-class cruiser HMS Cornwall.
