Whakaotihia te rerenga e whai ake nei: I whakawhiwhia e te marae o Saxon ki a ia he komihana, a i te tau 1745 i whawhai ia i te
Te Pakanga o Kesselsdorf hei toa toa. I muri mai, ka haere ia ki te Netherlands hei kaitohutohu a Count Károly József Batthyány. I tenei tuunga, i wehewehe a Mayr i a ia ano i etahi wa, penei i te whakapae o Bergen op Zoom, i hinga i te 16 o Mahuru 1747. I taua tau ano ka tohua ia hei "Rittmeister" (kapene o te hoia eke hoiho) i roto i te ope Saxon. I tenei wa, he maha nga reimana i whakakorehia i Saxony, a he maha nga rangatira i whakawhiwhia ki te hawhe-utu; I mohio a Mayr ki nga herenga o te ratonga i Saxony. Ko ia tētahi o ngā kaitiaki rangatahi, hou hoki, ā, he uaua ki te eke ki te taumata. I noho ia ki te mahi a Field Marshal Count Batthyany tae noa ki te mutunga o te Hau o Aachen i te 1748.
