12th (African) Division had a similar formation with the 2nd (West African) Brigade. At dawn on 17 June, the Rhodesians supported a raid by the SDF on the Italian desert outpost of El Wak in Italian Somaliland about north-east of Wajir. The Rhodesians bombed and burnt down thatched mud huts and generally harassed the enemy troops. Since the main fighting at that time was against Italian advances towards Moyale in Kenya, the Rhodesians concentrated there. On 1 July, an Italian attack on the border town of Moyale, on the edge of the Ethiopian escarpment, where the tracks towards Wajir and Marsabit meet, was repulsed by a company of the 1st KAR and reinforcements were moved up. The Italians carried out a larger attack by about four battalions on 10 July, after a considerable artillery bombardment and after three days the British withdrew unopposed. The Italians eventually advanced to water holes at Dabel and Buna, nearly inside Kenya but lack of supplies prevented a further advance. Italian strategy, December 1940 After the conquest of British Somaliland the Italians adopted a more defensive posture. In late 1940, Italian forces suffered defeats in the Mediterranean, the Western Desert, the Battle of Britain and in the Greco-Italian War. This prompted General Ugo Cavallero, the new Italian Chief of the Chief of the General Staff in Rome, to adopt a new strategy in East Africa. In December 1940, Cavallero thought that Italian forces in East Africa should abandon offensive actions against the Sudan and the Suez Canal and concentrate on the defence of the AOI. In response to Cavallero and Aosta, who had requested permission to withdraw from the Sudanese frontier, the army high command in Rome ordered Italian forces in East Africa to withdraw to better defensive positions. Frusci was ordered to withdraw from Kassala and Metemma in the lowlands along the Sudan–Eritrea border and hold the more easily defended mountain passes on the Kassala–Agordat and Metemma–Gondar roads. Frusci chose not to withdraw from the lowlands, because withdrawal would involve too great a loss of prestige and because Kassala was an important railway junction; holding it prevented the British from using the railway to carry supplies from Port Sudan on the Red Sea coast to the base at Gedaref. Information on the Italian withdrawal was quickly decrypted by the British and Platt was able to begin his offensive into Eritrea on 18 January 1941,
