After the fall of Salonica, the Greek objective was Janina, connected with the port of Preveza by an excellent road about sixty-three miles long. Directly Preveza fell into Greek hands, the authorities were faced with the problem of provisioning an army, in the first instance consisting of 15,000 men and gradually augmented to 60,000, operating against a fortified town in a totally barren country intersected by huge mountain ranges. The front of the army extended for about a hundred miles, and only one good road was available from the base to the centre of the advanced positions. Under these conditions, the authorities realised the possibilities of motor transport, and about thirty motor lorries, mainly obtained from Italy, were shipped to Preveza and put into service. It was found that each lorry could, in three hours, carry to the front about enough food for 1,000 men. This, however, was not the only problem. The army was absorbing on the average one ton of ammunition per day for every thousand men. The lorries were only capable at the best of handling 2-ton loads, and consequently were kept more than fully occupied. Moreover, the road, though good in certain portions, was in others particularly dangerous, being very winding and hewn for the most part out of the side of a precipice. Heavy traffic and heavy rains contributed to make the conditions yet worse, and under the circumstances, it is not surprising that very serious accidents occurred, and that by the end of the first six weeks only nine out of the original thirty lorries were still upon the road. It then became necessary to replenish the supply, which was managed in one way or another, and the service was maintained with enormous difficulty under conditions of false economy, which dictated considerable purchases of unreliable secondhand machines. Even so, the results served completely to convince Captain Trapmann that motor transport was the only solution of the supply problem in warfare.
