Cause

Italian forces advancing northward along a road toward Berbera, the capital of British Somaliland, reached the Tug Argan gap in the Assa hills, where British imperial troops had established fortified defensive positions across the narrow passage to block the invasion.

Event

Over four days of fighting from 11 to 15 August 1940, Italian infantry assaulted the British-held hilltop positions across the Tug Argan gap. Despite defending fortified ground, the British garrison was undermanned and was ultimately overrun, forcing a withdrawal toward Berbera.

Consequence

With the Tug Argan gap lost, the British position in Somaliland became untenable and the garrison was evacuated by sea. Italy rapidly secured the entire territory, gaining a propaganda victory for the Fascist regime, though the strategic value of the conquest was limited.
