This expedition unearthed a great wall which connected the forts at Semna South and Semna West. This wall strengthened the view that the military fortifications in the Semna region were built by the Egyptians in response to the “strong pressures and infiltration attempts on the part of southerners during the 12th Dynasty, allusions to which are found in the well-known Semna Stela and Semna Dispatches”.[17] Žabkar and Žabkar (1982) speculate that perhaps there was a complex of fortifications which embraced Semna South and West, and perhaps other forts in the region, but there is no definitive evidence for such a complex.
