On July 19 the siege was renewed by land, guns were mounted on the spires of St.Salvator's College chapel and on the Cathedral, and did much scathe, though, during the first three weeks of the siege, the garrison "had many prosperous chances." Meanwhile Knox prophesied the defeat of his associates, because of "their corrupt life." They had robbed and ravished, and were probably demoralised by Knox's prophecies.
On the last day of July the castle surrendered.

{24} Knox adds that his friends would deal with France alone, as "Scottish men had all traitorously betrayed them." Now much of this narrative is wrong; wrong in detail, in suggestion, in omission.

That a man of fifty, or sixty, could attribute the attacks on Beaton's murderers to mere revenge, specially to that of a "wanton widow," Mary of Guise (who had, we are to believe, so much of the Cardinal's attentions as his mistress, Mariotte Ogilvy, could spare), is significant of the spirit in which Knox wrote history.

He had a strong taste for such scandals as this about the "wanton widow." Wherever he touches on Mary of Guise (who once treated him in a spirit of banter), he deals a stab at her name and fame.

On all that concerns her personal character and political conduct, he is unworthy of credit when uncorroborated by better authority.
