Of the papyrus; Anastasi III records the daily passage of individuals in either direction in the time of Merneptah, while Anastasi VI illustrates the entry of an entire tribe coming from Edom into the Wadi Tumilat during a drought. But the most revealing document for the purpose of confirming Israel’s exit route, reports on the escape of two slaves from the royal residence at Pi-Ramesses, Anastasi IV. 
The author, a high ranking military commander, has been tasked with the capture and return of these two fugitives. This undertaking is similar to the one pharaoh’s chariot force had been tasked with in the Exodus story. The route taken by these two escapees has several striking parallels to the Exodus account. Both points of departure, for the two slaves and Israel, was Ramesses. Their time of departure is also roughly identical, with the two slaves first leaving under the cover of darkness and heading on to Tjeku (Pithom) and the Wadi Tumilat. Similarly, the Israelites departed at midnight and traveled on to Succoth (Pithom and the Wadi Tumilat region). We then hear of the escapees north of the fortress Migdol, beyond the present day city of Qantara and the Suez Canal. Again, the Israelites camped before Migdol, the point at which the ensuing chariots of pharaoh are first sighted.  Papyrus Anastasi IV therefore supports the geographical information that can be extracted from the Exodus account and also supports a hypothesis for a Ramesside period departure date (c.1295-1069 B.C.E.).
The ongoing excavations at Qantir (Pi-Ramesses) has revealed that the royal stables were capable of housing 460 horses and are the largest known stables in the ancient world. This suggests a chariot force in excess of 200 chariots were located at Pi-Ramesses during the Ramesside era. The normal ratio was fifty chariots for every five thousand infantry. While this ratio is for a fighting force on campaign and may not reflect the army at rest, the chariots had to be maintained and the horses had to be fed, indicating that the military presence in and around the region would have been very substantial and aids us in confirming our Iron Curtain image for the region.
