Once again he established himself in the Kasr Hassuna. Here he indulged in severe religious observances and urged the people to pray for divine help against the Unbelievers who had destroyed the Senussi army on the coast. In January Sayed Ahmed and Mohammed Saleh, his second in command, were considering retiring to Jerabub, so as to be still further away from the British. On the 2nd of February a force of armoured cars, lorries and light cars arrived a few miles north of Girba, a little oasis in a deep rocky valley north-west of Siwa. On the following day the cars successfully descended the pass and attacked the enemy camp at Girba. The Senussi were absolutely astounded. They had already learnt to fear the British cars, but they never for one moment thought it possible that a large force of motors could dash across the desert from the coast, almost 200 miles, and attack them in their stronghold. Owing to the rocky ground the cars were unable to get at close quarters with the enemy. The action lasted a whole day. The Senussi, who numbered about 800, were under the command of Mohammed Saleh, and another force of about 500 men were at Siwa with Sayed Ahmed. At the first alarm the Grand Sheikh bundled himself and his belongings on to camels and fled frantically over the sand-dunes towards Jerabub, followed by a straggling mob of Arabs. On the evening of the 4th the enemy began to retire from their position at Girba, burning arms and ammunition before evacuating, and on the 5th of February the cars entered Siwa and the British force was received by the sheikhs and notables at the Markaz with expressions of relief and goodwill. The column left the town on the same day and reached “Concentration Point,” north of Girba, on the following day. Another detachment had been sent to a pass above the western end of the oasis in order to intercept the fugitives, but only a few cars were able to get down from the high country above, but the one Light Car Patrol which did descend managed to cut off a number of the enemy who were retreating to the west. On the 8th February the whole column went back to Sollum. The enemy’s losses were 40 killed, including 2 Senussi officers, and 200 wounded, including 5 Turkish officers. Sayed Ahmed and Mohammed Saleh both escaped, but after this crushing defeat, and the capture of the Siwa oasis, all danger from the Senussi forces was at an end.
