In early 1574, a conflict took place between the Scottish and German mercenaries in Swedish service in Estonia. Under interrogation, the plot was exposed. Gilbert Balfour described the negotiations of Charles de Mornay, and
Pontus De la Gardie informed the king, who issued a warrant for Mornay's arrest. Four summons was issued for his questioning, but de Mornay took refuge in the Duchy of Duke Charles. In August 1574, Charles de Mornay was arrested when trying to escape Sweden by ship from
Nyköping. He was arrested by order of Duke Charles. Mornay was put on trial in Stockholm on 11 August. The trial was highly sensitive because it implicated a number of people of power, such as the king's brother Duke Charles as well as foreign people of power. Duke Charles was not summoned but left a written testimony implicating Mornay without implicating himself. Another important witness was Duke Charle's English servant Sigfrid Preston, and the testimonies of the Scottish mercenaries, notably that of Gilbert Balfour. Charles de Mornay admitted his guilt. It was never made clear who participated in the plot. However, it is noted, that the suspected conspirators
Hogenskild Bielke,
Gustaf Banér and Pontus De la Gardie, often gathered at meetings in the apartment of
Princess Elizabeth of Sweden, meetings where
Princess Cecilia of Sweden had also frequently been seen, and the two sisters and their brother Charles were somewhat compromised though they were never accused. Charles de Mornay also revealed, that one of the things which were agreed upon by the conspirators was to raise the dowry of Elizabeth from 100,000 to 150,000, so to make it possible for her to make a marriage of higher status. It is noted, that the marriage between Elizabeth and Henry III of France, which was officially suggested in 1574, could have been informally suggested through Charles already the year before, and that the French ambassador had expressed himself impressed by everything regarding Elizabeth with the exception of her dowry. It seems that John III suspected Cecilia to have prepared a rebellion against him: in 1573, he gave an order that Cecilia was not to be allowed in the Stockholm Castle during his absence, and in 1574, after the plot had been exposed, he gave orders to the governors in Östergötland to keep Cecilia under watch and not to let her have access to any royal castle. On 29 August, Charles de Mornay was sentenced guilty as charged for treason against King John III as well as having caused the execution of the innocent Hugh Cahun. Duke Charles was, if not an active participant so at least aware of the plot without trying to prevent it – but his part in the affair was silenced by order of the king. Duke Charles applied for mercy for Charles de Mornay on behalf of the noblemen Erik and Johan Sparre, nephews of Mornay's Swedish wife Anna Trolle, but without success. Mornay was executed in Stockholm on the 4 September 1574. Archibald Ruthwen and Gilbert Balfour were also executed. ==See also==
