In Lower Nubia, Intefiqer is known from several rock inscriptions, showing that he was part of a military mission into this region. He appears in an inscription found at the Red Sea coast and in the so-called Reisner Papyrus. Two rock inscriptions in Lower Nubia mention him. They seem to indicate that he was involved in a military campaign into this region.[3] The inscriptions are not dated, but other inscriptions in the region seem to indicate a military campaign in year 29 of Amenemhet I, which corresponds to the 9th year of Senusret I.
At Wadi el-Hudi, Intefiqer is known from a stela dated to a year 20, reporting the bringing of amethyst.[4]
