To sum up, the troops of the A.F.O. and of the I Serbian Army were supplied by the Monastir railway as far as Florina and Sakulevo, by the Florina-Armensko décauville and the Pisoderi telepheric, and the Sakulevo-Brod décauville with its extensions; the II Serbian Army by the railway as far as Vertekop and thence by décauville; the I Group of Divisions by the Vardar railway to Karasuli and thence by road; the British XII Corps by rail to Sarigöl and Kilindir and thence by décauville; the British XVI Corps, as long as it was on the Struma, by rail to Guvesne and thence by road to the Struma, whence a décauville reached various sectors; the brigade on the lower Struma, by rail to Arakli and thence by décauville. When the XVI Corps was moved to the area east of Lake Doiran, it was supplied by the same routes as the XII Corps, while the communications to the Struma now served the Greek I Corps. Everywhere the inadequacy of the railways was made good by the excellent M.T. services, and this not only for the areas where there were no railways at all, because the motor lorries helped to intensify transport even towards sectors served by railways, the carrying capacity of the latter being wholly inadequate to the immense needs of the armies. The British and French had several thousand lorries, we had about 400, the Greeks and Serbs were supplied by French and British lorries. If communications between the base at Salonica and the various sectors of the front had been rendered fairly satisfactory, lateral communications were extremely difficult, and this was particularly felt during the September offensive, when it was frequently necessary (though not so often as was expected beforehand) to transfer troops and artillery from one sector to another.
