British Waterloo Medal named (engraved) to “Cornet Otto B. Bülow 2nd Light Drags, KGL”. Cornet was a cavalry rank equivalent to the modern rank of 2nd Lieutenant. The Waterloo roll lists him as Otto Baron Bülow. This was apparently a mistranslation of "von Bülow" and was engraved on the medal as "B. Bülow". (The umlaut is very faint on the medal but is present.)
Otto Wilhelm Friedrich Joachim Karl von Bülow was born in 1795 and was commissioned into the King's German Legion in October, 1813. The published history of the KGL credits him with participation in the 1814 campaign in the Netherlands in addition to Waterloo. After the KGL was disbanded in 1816 Bülow joined the Hanoverian Guard du Corps. He was awarded the Wilhelm's Cross for 25 years service in 1838 and retired as a Captain (Rittmeister) in 1843. Rittmeister Bülow died in Lüneburg in 1872.
