Friedrich Balduin, Baron von Gagern (1794–1848) was a German soldier.
He entered the University of Göttingen, but soon left, and, taking service in the Austrian army, took part in the Russian campaign of 1812, and fought in the following year at Dresden, Kulm and Leipzig.
He then entered the Dutch service, took part in the campaigns of 1815, and, after studying another year at Heidelberg, was member for Luxembourg of the military commission of the German Federal Diet (1824, 1825).
[1] In the spring of 1848 he was in Germany, and on the outbreak of the revolutionary troubles he accepted the invitation of the government of Baden to take the command against the insurgent "free companies" (Freischaaren) in the Hecker Uprising led by Friedrich Hecker.
At Kandern, on 20 April, he made a vain effort to persuade the leaders to submit, and was about to order his troops to attack, when he was mortally wounded by the bullets of the insurgents.
