"A" Squadron arrived at Hamadan on June 7th. At this time General Bicherakoff's troops were concentrating at Manjil. The Jungalis under Kuchik {255} Khan were prepared to permit the Russian forces to continue their withdrawal to Russia, but were opposed to the passage of any British troops through their territory to Enzeli, a port on the Caspian. General Bicherakoff refused to sever his connection with the British, and prepared to attack the Jungalis who were entrenched covering Manjil Bridge. He applied to General Dunsterville for such assistance as he could give. Orders were received by the Brigade on June 8th for all cars to proceed to Kasvin, to take part in these operations. The cars were much in need of overhaul after their long trip from Bagdad, and the work of getting them ready for the road was pushed forward as fast as possible, cars as they became ready being sent forward. One battery left Hamadan on June 9th, and the whole squadron was on the road by June 13th. At this point the Rubberine tyres with which the cars were fitted gave considerable trouble, and failed to stand the wear necessitated by running over metalled roads. The average mileage per tyre worked out at 60 instead of 500 miles, and spares were soon used up. To obtain further supplies from railhead 400 miles distant necessitated a delay of at least ten days. By stripping some cars it was possible to maintain the others on the road, but by June 27th only two cars were mobile. As regards the failure of Rubberines, it must be remembered that these tyres are solely intended for {256} work in action, and not for long-distance running. However, pneumatic tyres had not been sent from England, and efforts to supply the deficiency by local purchase failed. Some tyres were purchased, but it was not possible to get the necessary fittings to enable Warland rims to be efficiently converted to take the pneumatics. As soon as the abnormal expenditure of Rubberines was experienced, arrangements were made to maintain a sufficient supply, and the cars were not off the road again on this account, although they consumed in one month 75 per cent. of the estimated year's supply. Considering that a single Rubberine tyre weighs 200 pounds, the strain imposed on the transport of the Brigade in maintaining a sufficient supply was considerable. From June 13th to July 20th the cars were mainly employed on convoy duties, and for defensive purposes at Resht and Manjil. On June 28th one armoured car was in action along the Kasmar road, supporting infantry who were attempting the rescue of an A.S.C. officer who had been captured by the Jungalis. Captain J. Macky was wounded in this engagement.
