By October, Sir A. Murray was ready to reoccupy Baharia, and ordered the new Western Force commander, Major-General W. A. Watson to commence operations against it. News leaked to Sayed Ahmed, who had advanced from Dakhla to Baharia with most of his force. Ahmed retreated to Siwa from 8–10 October. An attempt was made to try and cut off the rear guard by a concentration of light cars but despite their weakened state due to hunger and illness they were able to escape.
The "warders of the desert"
It was now known that the force in Dakhla was much smaller and likely to retire soon. Watson decided to attack from Kharga. The force contained sixty men with a Rolls-Royce armoured car and a tender, six Fords and twelve motorcycles, two Vickers and two Lewis guns supported by a company of the Camel Corps. The cars reached Dakhla on 17 October, 48 hours ahead of the Camel Corps, but it was found that most of the Senussi had gone, apart from a party of about 120 men at Budkhulu in the middle of the oasis, who were taken prisoner. With the arrival of the Camel Corps on 19 October, 40 more prisoners were taken. With further patrols in the area the oasis and its 20,000 occupants had been cleared of the Senussi by the end of October. Garrisons were installed at Dakhla and Baharia and civilian government restored.
The Senussi had played the game, from their point of view, extremely well. That had kept a very considerable force from participating in the war against the Turks for many months. The result had been the expenditure of vast resources in building the block houses and the railway, all now of limited value. They had waited until the last possible moment when the block house line was completed and the railway very nearly so, before disappearing.
Sayed Ahmed was attacked and defeated at Siwa at the beginning of February 1917, by a force of aroured cars from Sollum under Brig.-General H.W. Hodgson. This finally liquidated the Wester Desert campaign by discrediting Sayed Ahmed and destroying his influence.
