According to William Patten, Pedro de Negro was knighted by the Duke of Somerset following the battle of Pinkie and the capture of Leith on 28 September 1547 at Roxburgh Castle.[15] Somerset told a French diplomat Odet de Selve about the exploit, or "belle hystoyre" of 400 arquebusiers who each carried 20 pounds of powder through the Scottish lines into the town.[17] A cavalry force led by Thomas Palmer was defeated by the French on 16 July, a loss described by Ulpian Fulwell in his Flower of Fame (London, 1575), and by John Knox in his History.[18] At the end of July, the French diplomat Odet de Selve reported that the delivery of the bags of gunpowder and the efforts of "Pietro Negro" and "Captain Windent" were the talk of the court in London.[19] However, some doubt remains about the date of their exploit, Thomas Fisher wrote on 30 July that Baynbridge was preparing a second convoy of men and powder, while a coded note from James Wilsford, the Captain of Haddington, dated 3 August, discusses a plan with horsemen carrying powder as a future event, and Wilsford says the town could not support their horses.[23] A chronicle of the reign of Mary, Queen of Scots mentions the defeat and capture of Spanish soldiers led by "Julius Romanus", Julián Romero, near Coldingham in the spring of 1549.She wrote in favour of the Spanish cavalrymen (who owed money to her villagers) to Mary of Guise in March 1549, that they behaved "like noble men, and also the Mour, he is as sharp a man as rides, beseeching your grace to be a good princess unto him".
