[3] Meutas and other courtiers formed the Fraternity of Saint George, a group dedicated to archery and hand guns said to be a forerunner of the Honourable Artillery Company.
He may have been in a group of 30 "richly apparelled" gentlemen of the king's household who met Anne of Cleves at Calais in December 1539, and he and his wife were listed in the royal retinue appointed to meet her at Dover.
[7] Henry VIII was considering marrying her, and apparently encouraged by Meutas's report, sent Philip Hoby and Hans Holbein the younger to make a portrait.
[8] In 1539 Henry VIII gave Meutas and his wife the site of the monastery at Westham with Richard's Chapel, known as Stratford Langthorne Abbey, in Essex.
[9] Peter Meutas led a band of "hagbutters" at the Burning of Edinburgh in May 1544, the first major action of the war now known as the Rough Wooing.
[12] The English commander, Lord Hertford described this battle as a half-hour fight, "right sharply handled on both parts", with Peter Meutas's hagbutters giving "right honest service".
[19] Meutas and Thomas Bishop brought news of this setback to Catherine Parr and the council at Woking Palace on 19 September and were directed to Henry VIII at Boulogne.
Meutas organised the building of some fortifications, employing the military engineer John Rogers, and a tower at Castle Cornet was known as the "Mewtis Bulwark".
Four English cannons bombarded Thornton while foot soldiers with hand guns directed by Peter Meutas prevented the defenders shooting from the gunloops.
[26][27][28] In August, 1559, Matthew Stewart, 4th Earl of Lennox, recommended Meutas to Elizabeth I as "a fytte manne", suitable to perform diplomatic duties in France, acceptable to the French court, and also able to promote the Protestant religion.
[30] In Paris, Meutas and Nicholas Throckmorton were served dinner on plates engraved with heraldry claiming the title of Mary, Queen of Scots, to the English throne.
[38] Meutas returned to London with a letter from William Maitland of Lethington, which argued that Henry VIII would never have intended that the offspring of Margaret Tudor would be barred from the throne of England.
[40] Elizabeth was not fully satisfied by the answers to her requests and Mary's refusal to ratify the treaty, as reported by Meutas, and she asked Thomas Randolph to continue the discussion.
