Mischief he did, to little purpose.
The child queen was conveyed to an isle in the loch of Menteith, where she was safe, and her marriage with the Dauphin was negotiated.

In June 1548 a large French force under the Sieur d'Esse arrived, and later captured Haddington, held by the English, while, despite some Franco-Scottish successes in the field, Mary was sent with her Four Maries to France, where she landed in August, the only passenger who had not been sea-sick! By April 1550 the English made peace, abandoning all their holds in Scotland.

The great essential prize, the child queen, had escaped them.
The clergy burned a martyr in 1550; in 1549 they had passed measures for their own reformation: too late and futile was the scheme.

Early in 1549 Knox returned from France to England, where he was minister at Berwick and at Newcastle, a chaplain of the child Edward VI., and a successful opponent of Cranmer as regards kneeling at the celebration of the Holy Communion.

He refused a bishopric, foreseeing trouble under Mary Tudor, from whom he fled to the Continent.
