But there were other obvious objections. To switch any force worth bothering about from northern France to the Friuli flats was bound to be a protracted process, because only two railways led over the Alps from Dauphine and Provence into the basin of the Po; and those lines were distinguished for their severe gradients. It was, as a matter of fact, incomparably easier for the enemy to mass reinforcements in the Julian Alps than it was for the two Western Powers to mass reinforcements in the low ground facing that great area of rugged hills. The question of a transfer of six divisions from the Western Front to Venetia had, however, been gone into very thoroughly by the General Staff in view of conceivable eventualities. An elaborate scheme had been drawn up by experienced officers, who had examined the question in consultation with the Italian military authorities, and had traversed the communications that would have to be brought into play were such a move to be carried out. What time the transfer would take was a matter of calculation based on close examination of the details. The final report came to hand while I was acting as Deputy C.I.G.S., although its general purport had already been communicated several weeks before. Two or three months later, when it suddenly became necessary to rush British and French troops round from northern France to the eastern portions of the Po basin after the singular _debacle_ of Caporetto, actual experience proved the forecasts made in this report to have been quite correct. There was not much "rushing" about the move. It took weeks to complete. General Pershing and his staff arrived in England just at this time, and I enjoyed the pleasure of meeting them and discussing many matters. The attitude of these distinguished soldiers, one and all, impressed us most agreeably. One had heard something about "Yankee bounce" in the past, which exists no doubt amongst some of the citizens of the great Republic across the water. But here we found a body of officers who, while manifestly knowing uncommonly well what they were about, were bent on learning from us everything that they possibly could, and who from the outset proved themselves singularly ready to fall in with our methods of doing business even where those methods differed widely from what they had been accustomed to.
