2nd and 5th Brigades crossed the Abyssinian border north of Dukana late afternoon on 31 January 1941, moving in parallel columns to assault the Italian positions in the Mega-Moyale complex.Moyale: 2nd Italian Brigade HQ, 12th Colonial Infantry, 105th Blackshirt Battalion and the 25th Artillery Pack Battery.Klein II, p. 110</ref> The Italians had well established and entrenched advance positions at Goai Crater, El Gumu and Hobok which were to be taken before the main forces at Mega-Moyale could be attacked. 2nd Brigade was assigned to attack Gorai on the right, while 5th Brigade was to assault El Gumu. The attack commenced early morning on 1 February and by 1600 both objectives had been secured. The armoured cars however failed to cut off the remnant Italian forces, and they retreated back towards Mega and Moyale. The next day, 3rd Transvaal Scottish and the armoured cars attacked Fort Hobok, sited on a ridge 30 km west of El Gumu supported by artillery. The armoured cars again covered the flanks and tried to cut off any retreating forces. By afternoon, the fort had been captured. The 2nd Brigade now held Gorai and the 5th Brigade, Hobok ("Map 1: Point 1"). It was again hoped that these raids would ignite the Shifta uprising, but as with the previous occasion, this never materialised.
