Damascus was 150 miles (240 km) from the EEF bases and Aleppo was 200 miles (320 km) beyond Damascus.
The most difficult problem caused by these great distances was the provision of food and medical comforts, because a regular supply service could not be maintained along the lines of communication.

Captured ports were quickly organised as advanced bases, for supplying both Bulfin's XXI Corps and Chauvel's Desert Mounted Corps, advances.
Supplies began to be landed at Haifa on 27 September with 1,000 tons landed each day during the first week of October, but the infrastructure was lacking for moving the supplies the 85 miles (137 km) from Haifa to Damascus and 73 miles (117 km) from Afulah to Damascus, with a corps depot established at Samakh and carried in lorries on to Damascus.

At the beginning of the pursuit, the supply route ran from Haifa, to Nazareth and on to Tiberias and Samakh, but by the time Desert Mounted Corps reached Damascus the corps had outrun its supply columns.
The main problems were damage to the railway from Haifa to Samakh, which was repaired by 30 September, and the very bad condition of a two-mile (3.2 km) stretch of road from Jisr Benat Yakub towards Quneitra.
The stretch of "less than a mile leading up from the crossing of the Jordan at Jisr Benat Yakub", took on average a day to a day and a half to negotiate.
It took three days by motor lorry to travel the 90 miles (140 km) from Semakh to Damascus. "
There was only one narrow and winding road, running to the south-west and crossing a narrow bridge which broke down several times and was only wide enough for one vehicle.
Most of the troops were camped along this road, on the outskirts of the town, and, since it was the only route by which they and the motor supply lorries from Semakh railhead could reach the town, it was frequently blocked."

On 4 October 1918 the ration convoy broke down leaving the 12th Light Horse Regiment short two meals.
From 19 October supplies and rations of tea, milk and sugar were landed at Beirut and carried on lorries to Damascus and Baalbek for the two cavalry divisions.

On 22 October Allenby reported:
I am at work on the broken bridges in the Yarmuk Valley; and, meanwhile, bridging the gap by camels and motor lorries.
As for roads, I propose to concentrate on the coast road from Haifa northwards, then Tripoli–Homs road, and then Beirut–Baalbek road.
I hope to keep them passable during the rains; then, with my standard gauge railway to Haifa, and using the Turkish railway Haifa–Damascus–Rayak, I may keep going.
The railway, N. of Rayak, is standard gauge; and sleepers are steel, so that I can't squeeze the line in to the metre gauge; therefore, I fear it is useless to me, as yet.
