He was the son of the landed gentleman and Swedish Empire army officer Henrik Gotthard von Buddenbrock (1648–1727) and Charlotta Cronman.

[1] On 23 August 1741 (3 September 1741) Swedish Major General Carl Henrik Wrangel and his corps in Villmanstrand in Karelia, at the long disputed frontier between Sweden and Russia, was attacked and defeated by a Russian army under General Peter Lacy before Buddenbrock, less than 10 kilometers away, could come to his assiantance.

A court martial was convened under Field Marshal Hugo Johan Hamilton (sv) on 8 October to investigate the two cases.

Buddenbrock was accused of, among other things, not assembling his troops in a timely fashion to cross the Russian border, as planned.

In an appeal, Buddenbrock wrote a comprehensive account where he detailed his services to the kingdom, but despite this and the pleading of his family, the verdict was confirmed by the Estates the following day.
