truck so that the payload of 2 tons was the maximum. However, by 1944 the charcoal trucks were being operated successfully over the Luhsien road with its high altitude as well as all the other routes. Charcoal was obtainable in most villages and was cheap in the mountain areas and the cost, per ton carried, was 1/5 of that of alcohol. The charcoal burners carried the major load of supplies through 1944 and the first part of 1945.
The successful Burma campaign of autumn 1944, the opening of the Ledo road and the petrol pipeline laid along it made a great difference to the Unit transport systems. Not only was the Unit allocated 25 Canadian W.D. 3-ton Dodge trucks in the summer of 1945 from ARC and UNRAA, but it was also able to obtain P.O.L. (Petrol, Oil and Lubrication) supplies from the US army free of charge. To quote from a letter written 10/6/45 “It was a great moment when at Kunming, Rupert (Stanley) and I drove up in a truck to the P.O.L. station and pulled up beside a real petrol pump (and bright red at that too) and said to the Sergeant "Fill'er up" and he filled her up to the tune of 22 gallons US. When I told him it was 34 years since I'd done that he registered the usual GI amazement that anyone could stand the place that long”.
System Performance
The cargo carried by the system was in three categories: Medical and Relief supplies for NHA, IRC, ARC etc.; FAU maintenance and fuel supplies; and return cargoes. The Government transport administration ruled that no trucks should travel empty and on return journeys must take Government, usually military, cargoes. The Unit had a special pass, as a Christian pacifist organization, exempting it from taking soldiers or weapons and instead usually had cargoes of salt from the Yangtse valley south to Kweichow and Yunnan.
The system performance figures in terms of kilometre tons for the 4 years, as far as they are at present available, are given in Table VII. The number of trucks available on average through the years are given, and from this it will be seen that the operating efficiency in terms of kilometre tons per truck per year steadily increased. This was due to:---
1) increased efficiency of the Charcoal truck operations, more than compensating for the deterioration of the diesel trucks
