OBSERVATIONS.
1º. “Attack vigorously, after having observed well where to strike.” This simple, but profound expression in Napoleon’s letter of service, forms the test by which the prince of Esling’s operations should be judged.
2º. The design of turning the strong ground behind Celerico, by the route of Viseu, required close and rapid movements; yet the French general did not quit Viseu, to march against Coimbra, until the tenth day after passing the Pinhel. This was not a “a vigorous attack.”
3º. Massena should have brought the allies to action in a forward position; and he might have done so either when Almeida fell, or before that event, because the complement of mules for the service of the army not being then full, the commissariat was dependent upon the country carts; and when the first retrograde movement took place from Alverca, the drivers fled with their animals, producing infinite confusion in the rear. The commissary-general Kennedy contrived, indeed, to procure fifteen hundred additional mules; but, intermediately, a brisk advance of the enemy would have forced the English general to fight, or retire more hastily than would have beseemed his reputation, or suited his political position.
4º. If the prince of Esling had not been misled by Alorna and Pamplona, and the more readily that the estates of the latter were situated about Coimbra, he would have judged that the line his adversary had studied for eight months, and now so carefully and jealously guarded, was more likely to afford advantages, than the circuitous route by Viseu, which was comparatively neglected. The French general, ill acquainted with the scene of action, but having the stronger and more moveable army, should have followed closely.
A rapid pursuit, through Celerico, would have brought the French army on to the Alva before Hill or even Leith could have joined lord Wellington. The latter must then have fought with half his own army, or he must have retreated to the Lines. If he offered battle, his position could be turned either by the right or left; on the left by the slopes of the Estrella, on the right by crossing the Mondego, for Busaco was too extensive to be occupied before Hill and Leith arrived. Now, the road by Viseu being the longest and least practicable, demanded great diligence to compensate for the difficulties of the way, and to gain Coimbra and force the allies to a battle before Hill arrived, were objects more readily to be attained by the left bank of the Mondego. The point where to strike was therefore not “well considered,” and it is clear that Massena did not rightly estimate the greatness of his enterprise.
5º. When the rocks of Busaco glittering with bayonets first rose on the prince of Esling’s view, two fresh questions were to be solved. Was he to attack or to turn that formidable post? Or, availing himself of his numerical strength and central situation, was he to keep the allies in check, seize Oporto, and neglect Lisbon until better combinations could be made? The last question has been already discussed; but, contrary to the general opinion, the attack upon Busaco appears to me faulty in the execution rather than in the conception; and the march by which that position was finally turned, a violation of the soundest principles of war. In a purely military view, the English general may be censured for not punishing his adversary’s rashness.
With respect to the attack, sixty-five thousand French veterans had no reason to believe that fifty thousand mixed and inexperienced troops, distributed on a mountain more than eight miles long, were impregnably posted. It would have been no overweening presumption in the French general to expect, that three corps well disposed, supported by a numerous artillery, and led on the first day, (as Ney desired,) might carry some part of the position, and it is an error, also, to suppose that guns could not have been used: the light division were constantly within range, and thirty pieces of artillery employed on that point would have wonderfully aided the attack by the sixth corps. But when a general in chief remains ten miles from a field of battle, gives his adversary two days to settle in a position, makes his attacks without connection, and without artillery, and brings forward no reserves, success is impossible even with the valiant soldiers Massena commanded.
6º. “An army should always be in condition to fight.”
“A general should never abandon one line of communication without establishing another.”
