In the spring of 556 AD, Nachoragan began a new invasion by attacking Nesus with 60,000 men, where Martin and Justin were positioned.

[2] The Greek name Nachoragan (Ναχοραγάν) recorded by the Byzantine historians probably represents not a name but the Middle Persian title naxwaragān[3][4] or naxwārakān/naxwāragān.
[5] It corresponds to the Syriac nkwrgn (ܢܟܘܪܓܢ, "governor")[6] and the Armenian title nakharar, both of which are borrowed from Middle Iranian languages.
