22 to 28 November, Archimede and Galileo Ferraris sailed to investigate reports of a convoy but found nothing, as did Tigre, Leone, Daniele Manin, Nazario Sauro and Galileo Ferraris from 3 to 5 December. From 12 to 22 December Archimede sailed twice after ship sightings but both sorties came to nothing; Galileo Ferraris sortied off Port Sudan. from June to December the RAF had escorted 54 BN and BS convoys from which one ship was sunk and one damaged by Italian aircraft. French Somaliland 1940–1942 The governor of French Somaliland (now Djibouti), Brigadier-General Paul Legentilhomme had a garrison of seven battalions of Senegalese and Somali infantry, three batteries of field guns, four batteries of anti-aircraft guns, a company of light tanks, four companies of militia and irregulars, two platoons of the camel corps and an assortment of aircraft. After visiting from 8 to 13 January 1940, Wavell decided that Legentilhomme would command the military forces in both Somalilands should war with Italy come.

The British changed policy, with encouragement from the Free French, to "rally French Somaliland to the Allied cause without bloodshed". The Free French were to arrange a voluntary ralliement by propaganda (Operation Marie) and the British were to blockade the colony. Wavell considered that if British pressure was applied, a rally would appear to have been coerced.

In June, Nouailhetas was given an ultimatum, the blockade was tightened and the Italian garrison at Assab
