General Hill, menaced by D’Erlon with a very superior force, and having the pass of Maya, half a day’s march further from Pampeluna than the passes of Roncesvalles, to defend, could not give ready help. If he retreated rapidly D’Erlon could follow as rapidly, and though Picton and Cole would thus be reinforced with ten thousand men Soult would gain eighteen thousand. Hill could not however move until he knew that Byng and Cole were driven from the Roncesvalles passes; in fine he could not avoid a dilemma. For if he maintained the passes at Maya and affairs went wrong near Pampeluna, his own situation would be imminently dangerous; if he maintained Irrueta, his next position, the same danger was to be dreaded; and the passes of Maya once abandoned, D’Erlon, moving by his own left towards the Alduides, could join Soult in the valley of Zubiri before Hill could join Cole and Picton by the valley of Lanz. But if Hill did not maintain the position of Irrueta D’Erlon could follow and cut the sixth and seventh divisions off from the valley of Lanz. The extent and power of Soult’s combinations are thus evinced. Hill forced to await orders and hampered by the operations of D’Erlon, required, it might be three days to get into line near Pampeluna; but D’Erlon after gaining Maya could in one day and a half, by the passes of Berderez and Urtiaga, join Soult in the Val de Zubiri. Meanwhile Byng, Morillo, Cole, Campbell, and Picton would be exposed to the operations of double their own numbers; and however firm and able individually those generals might be, they could not when suddenly brought together be expected to seize the whole system of operations and act with that decision and nicety of judgment which the occasion demanded. It was clear therefore that Hill’s force must be in some measure paralyzed at first, and finally thrown with the sixth, seventh, and light divisions, upon an external line of operations while the French moved upon internal lines.
