He was the high priest of Anhur under Merenptah, but started his career as a military man, most likely under king Ramesses II (reigned about 1279–1213 BC).
According to this inscription he started his career on a ship, albeit it is not entirely clear what his exact position was there.
However, it seems likely that the service in the army was under king Ramesses II, as the second part of career happened under Merenptah.
[1] The biography states further more that Anhurmose was chosen by god Shu to become high priest of Maat.
Two sons are mentioned, they are called Pennub, who was stablemaster and Hui, who was priest of Anhur.
