Pontus De la Gardie

He was suspected to have taken part in the Mornay plot to assassinate John III. The plot was led by Charles de Mornay, who was in contact with Christina of Denmark and the French ambassador in Copenhagen Charles Dancay.[2] John III was to be killed during a sword dance performed by Scottish mercenaries at the party which was to be given in October that year before the Scottish mercenaries departure to the Baltic.[2] After the assassination, the king's brother Duke Charles was to be placed upon the throne.[2] The plot did not materialize as de Mornay lost his nerve and never gave the sign to the mercenaries to take action.[2] In September 1574, the plot was revealed and Charles de Mornay was arrested, interrogated and executed. 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.[2] Pontus De la Gardie was himself never put on trial for his suspected involvement in the affair.

After Clas Åkesson Tott's resignation as the supreme commander of the Swedish forces in Finland and Estonia as a consequence of the Siege of Wesenberg during the Livonian War, de la Gardie took over Tott's office.[3] De la Gardie's skills, combined with the fact that Sweden's enemy Russia had to transfer troops to defend against Polish attacks further south, led to considerable military success for Sweden during the following years. In the fall of 1580, Karelia was conquered. De la Gardie led his troops over the frozen Gulf of Finland to capture the fortresses of Wesenberg (now Rakvere) and Tolsburg (now Toolse). In September 1581, Narva was taken after a storming that had been preceded by a massive bombardment. 4,000 soldiers and civilians were killed, pointing out the fact that De la Gardie was not only a skillful warrior, but a cruel and hard commander as well. De la Gardie and his Swedish troops went on to capture the fortress of Ivangorod and several other fortresses that autumn. In 1582, the war with Russia ended and Sweden got to keep the conquests made in Karelia and Ingria, but had to withdraw from Livonia.[4]

De la Gardie was the most renowned military commander in Sweden during the 16th century and has been credited with much of the country's military success in the 1580s. An example of his ingenuity was the strategy of using zigzag shaped saps during the siege of Narva, a new technique at the time.[4]

De la Gardie drowned in the Narva River and is buried in St Mary's Cathedral of Tallinn. His tomb chest is made by well-known artist and architect Arent Passer.[5]
