Johan August Meijerfeldt the Younger

In 1744 he was promoted to the rank of captain, and the following year received royal permission to leave the country to fight in the War of the Austrian Succession on the side of Austria, first against Prussia and later against France.

[3][4] Back in Sweden he became a confidant of Queen Louisa Ulrika and aided her in trying to raise funds abroad for her failed coup d'etat in 1756.

He commanded forces fighting around Peenemünde, Güstrow and Wolin during the subsequent Pomeranian War.

With the outbreak of the Russo-Swedish War in 1788, he returned to active military service and initially commanded a brigade attempting to take Hamina, an effort which derailed due to a lack of supplies and ammunition.

In this capacity he reconquered Karkkila in July 1789, and managed to thwart further Russian gains in Finland.

Soon after the war he retired, in opposition to the increasingly authoritarian politics of King Gustav III.
