Ludwig Samson Heinrich Arthur Freiherr[a] von und zu der Tann-Rathsamhausen (18 June 1815 – 26 April 1881) was a Bavarian general.

He attended the manoeuvres of the Austrian army in Italy under Field Marshal Radetzky and, in a spirit of adventure, joined a French military expedition operating in Algiers against the Tunisian frontier.

In 1848 he was promoted to major, and in that year he distinguished himself greatly as the leader of a Schleswig-Holstein light corps in the First Schleswig War between Denmark and a coalition of German states.

The almost entirely unfavorable outcome of the military operations led to vehement attacks on him in the press, but the unreadiness and ineffectiveness of the troops and the general lack of interest in the war on the part of the soldiers had foredoomed the South Germans to failure in any case.

Transferred in the autumn to an independent command on the Loire, he conducted the operations against d'Aurelle de Paladines, at first with marked success, and forced the surrender of Orléans.
