Prince Carl Bernhard of Saxe-Weimar-Eisenach (30 May 1792 – 31 July 1862)[1] was a distinguished soldier, who, in 1815, after the congress of Vienna, became colonel of a regiment in the service of the king of the Netherlands.

Prince Bernhard's brigade (joined later by the 1st Brigade,) held the cross roads at Quatre Bras for almost 24 hours from the late afternoon of 15 June 1815, until about 3 p.m. on the 16 June, preventing Marshal Michel Ney with the left wing of the French L'Armée du Nord from taking the cross roads before the Duke of Wellington and substantial allied forces arrived to reinforce the 2nd Division and fight the Battle of Quatre Bras.

Though in the course of the battle Durutte's 4th French Division obtained a temporary foothold in Papelotte, it was never captured[4] Bernhard was appointed commander of the Dutch East Indies Army on December 6, 1848, and arrived on April 14, 1849, in Java.

A heavily edited account of his travels, Reise seiner Hoheit des Herzogs Bernhard zu Sachsen-Weimar-Eisenach durch Nord-Amerika, was published by the historian Heinrich Luden in 1828.

His residence in Batavia (now Jakarta) was later used for sessions of the Volksraad quasi-legislature of the Dutch East Indies and the Investigating Committee for Preparatory Work for Independence (BPUPK).
