The following year he rallied his forces and proceeded to capture Hamina, Porvoo and Hämeenlinna, by August encircling more than 17,000 Swedes near Helsinki and effectively bringing the hostilities to an end.

His son Franz Moritz von Lacy had entered the Austrian service in 1743 and became one of the most successful imperial commanders of the 18th century.
