Hostilities between the garrison of the Castle and the Regent’s forces, which were encamped at Leith, began on the 29th of April, with a skirmish at Lowsilea. Next day, Kirkcaldy issued a proclamation, commanding all who sympathised with Lennox, to leave the city within six hours, and requiring the citizens to be within doors, after nine o’clock every night. Two days later, he followed this up by demanding the keys of the city from the bailies, and setting his own men to guard the gates; and his next step was to plant artillery on the roof and steeple of St Giles’s. About the beginning of May, the Regent made an attempt to hold a Parliament, but was driven off by the Castle guns. On learning this, Queen Elizabeth made a great show of indignation. It was ‘necessary for her that the Regent and his party should not be ruined.’ Nor, indeed, did it suit her that either faction should obtain the upper hand independently of her. She consequently directed Sir William Drury to tell Grange and the noblemen joined with him, that she strongly disapproved of their conduct in preventing the Regent and his friends from holding a Parliament to appoint commissioners to treat with those of the Queen of Scots. In energetic language she desired him to ‘condemn Kirkcaldy of falsehood and untruth’ if it were actually the case that he had said, as had been reported to her, that Lennox was ‘sworn English against his country,’ and meant to deliver all the castles and strongholds to her; and to require him to give her full satisfaction on this point. She further instructed him to inform the Captain that, if he continued to increase the troubles of the realm, she would ‘judge that to be true which, by some had been long doubted, that he and his companions were partially disposed, for their own lucre and to maintain their disordered authorities, to continue these inward troubles, by pretending to favour the Queen, with whom it was known that, before time, they could not be content.’ If this should not be enough, Drury was to add “some sharper speech” of his own.
