The effect of leaving Adrianople in the hands of the enemy was that supplies for the army in the field coming from Bulgaria could travel by one of two routes. They could come through Yamboli to Kirk Kilisse, or they could come through Novi Zagora to Mustapha Pasha by railway, and then to Kirk Kilisse around Adrianople. From Kirk Kilisse to the rail-head at Seleniki, close to Chatalja, they could come not by railway, but by a tramway, a very limited railway. If Adrianople had fallen, the railway would have been open. The Bulgarian railway services had, I think, something over 100 powerful locomotives at the outset of the war, and whilst it was a single line in places, it was an effective line right down to as near Constantinople as they could get. But, Adrianople being in the hands of the enemy, supplies coming from Yamboli had to travel to Kirk Kilisse by track, mostly by bullock wagon, and that journey took five, six, or seven days. The British Army Medical Detachment, travelling over that road, took seven days. If one took the other road you got to Mustapha Pasha comfortably by railway. And then it was necessary to use bullock or horse transport from Mustapha Pasha to Kirk Kilisse. That journey I took twice; once with an ox wagon, and afterwards with a set of fast horses, and the least period for that journey was five days. From Kirk Kilisse there was a line of light railway joining the main line. But on that line the Bulgarians had only six engines, and, I think, thirty-two carriages; so that, for practical purposes, the railway was of very little use indeed past Mustapha Pasha. Whilst Adrianople was in the hands of the enemy, the Bulgarians had practically no line of communication. My reason for believing that it was not the original plan of the generals to leave Adrianople "masked" is, that in the first instance I have a high opinion of the generals, and I do not think they could have designed that; but think rather it was forced upon them by the politicians saying, "We must hurry through, we must attempt something, no matter how desperate it is, something decisive." In the second instance, after Adrianople had been attacked in a very half-hearted way, and after the main Bulgarian army had pushed on to the lines of Chatalja, the Bulgarians called in the aid of a Serbian division to help them against Adrianople. I am sure they would not have done that if it had not been their wish to subdue Adrianople. To be forced to invoke Serbian aid was a serious wound to their vanity.
