Gustav Wachtmeister
Gustav Wachtmeister was a Swedish Army officer made famous at the Battle of Valkeala in Finland in 1789 against Russia where he was wounded by a musket shot to his arm, which had to be amputated. He was made the hero of the hour by King Gustav III of Sweden who was in desperate need of publicity as he tried to silence domestic opposition with a crushing victory over Russia.
He was born into an aristocratic Swedish family in 1757 and as was common for sons of Swedish noble families, embarked on military life at a young age, receiving a commission as an ensign in 1772. In 1778 he went abroad to gain experience on campaign, joining the Prussian Army fighting Austria in the War of the Bavarian Succession from 177879.
