Whakaotihia te rerenga e whai ake nei: I whanau a Archduke Louis i Florence, Itari. I uru ia ki te Ope Taua o Austrian Imperial i te wa o te tamarikitanga, a, kaore i roa ka whiwhi ia i te taumata o Feldmarschal-Leutnant. Mai i te 1807 ki te 1809, ko ia te kaiwhakahaere matua o te rohe hoia. I te tau 1809, i tohua ia hei rangatira mo te V Armeekorps. I tēnei tūranga, i whawhai ia i ngā pakanga o
Abensberg, Landshut, me Ebersberg i te Paenga-whāwhā me te Haratua, i muri mai ka whakarerea e ia tana whakahau.
