The next war in which Bayard was engaged was that in which Louis XII. was attacked by the King of Spain in Navarre. Henry VIII. was at the same time preparing to invade the north of France, landing near Calais, and the Swiss were already pouring into Burgundy. As we may expect, Bayard was not long without being sent on some perilous adventure. He was at the siege of Pampeluna with the deposed King Jean d'Albret of Navarre and the lord of La Palisse, when they told him there was a certain castle about four leagues off which it would be well for him to take, as the garrison was a constant annoyance to the French. The Good Knight at once set off with his own company, that of Captain Bonneval, a certain number of adventurers, and two troops of "landsknechte." When he arrived before the fortress, he sent a trumpeter to proclaim to those within that they must yield it to their rightful sovereign, the King of Navarre, in which case they would save their lives and goods, but if the place had to be taken by assault they would have no mercy. The Spaniards were valiant men and loyal subjects of the King of Spain, and they made reply that they would not yield the fortress and still less themselves. Upon this Bayard put his artillery in position and made such good use of it that a breach was soon made in the walls, but it was high up and not easy to make use of. The Good Knight then sounded the order to assault and commanded the "landsknechte" to advance. Their interpreter said that it was their rule, when a place was to be taken by assault, that they should have double pay. The Good Knight would have nothing to do with their rules, but he promised that if they took the place they should have what they asked for. But not a single man of them would mount the breach. Thereupon Bayard sounded the retreat, and then made an attack with the artillery as though he wished to enlarge the breach, but he had another plan. He called one of his men-at-arms, by name Little John, and said to him: "My friend, you can do me a good service which will be well rewarded. You see that tower at the corner of the castle; when you hear the assault begin take ladders, and with thirty or forty men scale that tower, which you will find undefended." So it turned out, for all the garrison went to defend the breach, while Little John and his men mounted the tower unseen and cried out, "France! France! Navarre! Navarre!" The defenders, finding themselves assailed on every side, did their best; but the castle was soon taken, and the whole place was pillaged and left in charge of the King of Navarre's men. In this year, 1513, died Julius II., the great warrior Pope, a constant foe to the French, and he was succeeded by the Cardinal dei Medici, Pope Leo X.
