Yet another action must be briefly noticed to show the value set on English military skill. During the invasion of Portugal by the King of Castile, in 1385, the Portuguese were joined by a party of about five hundred English adventurers, whose leaders appear to have directed most of the operations. It was under their guidance that the decisive battle of Aljubarotta, of which the Portuguese are still proud, was finally fought; and it is worthy of remark that, finding no advantageous position to hand, they deliberately constructed by means of abattis an imitation of the position of Poitiers, making it unassailable from the front except through a narrow strait, which was purposely left open and lined with archers. Marvellous to relate, the Spaniards and the French, who were fighting with them, rushed straight into the trap, and were of course utterly overthrown; whereupon, in due accordance with precedent, the Portuguese made their counter-attack and won a complete victory.[27] All this was due, as Froissart says, to the counsel of the English; and indeed, little though we may be conscious of it, it is doubtful whether even after Waterloo the prestige of English soldiers was greater than at the end of the fourteenth century. But while the English military doctrines were thus spreading themselves over Europe, fresh innovations, which were destined to render them obsolete, were already making rapid progress. Artillery in the hands of the Germans was tending more and more to lose its cumbrous character and to take new form in mobile and practicable weapons. The heavy bombards, which could be neither elevated nor traversed, had before the close of the fourteenth century given place to lighter guns of smaller bore fixed on to the end of a shaft of wood and supported on a fork or hook, whence they derived their name of _Hakenbüchse_, a word soon corrupted by the English into hackbut, hagbush, and finally harquebus. A later improvement had fitted guns with a stock like that of the cross-bow, which could be brought up to the shoulder, thus more readily aligning the barrel to the eye. The step from this to the hand-gun, which could be served out as the individual weapon of a single man, was but a short one and was soon to be taken. But as the traditions of Wellington and the Peninsula were to be tried once more at Alma and Inkerman before they finally perished, so the system of the two great Edwards was to be revived forty years after Navarrete at Agincourt.
