No historic record of this, so the archaeologists are scratching their heads - evidence of two destructions, 10 years apart, of the Egyptian fortress at Jaffa - first around 1135 BC second 1125. "Culprits may well have been Philistines."

[Patrick Waterson]

"The destruction of the gate in 1135 B.C.E. was so violent that it completely brought down the 22-meter wide and 10-meter high superstructure. The gate was rebuilt, but what seems to be a second wave of destruction within no more than decade (circa 1125 B.C.E.) finally brought an end to Egyptian rule in Jaffa.

"The destruction of the Ramesses gate definitely happened," Martin agrees. "The question is when exactly - at the end of the Nineteenth Dynasty or already in the reign of Ramesses III?"

If using those dates, it already answers Martin's question: Ramses III, and posthumously.  Of the dates given, one would fall within the putative reign of Ramses VII and the other in that of Ramses IX (by current chronology).  For such a question to be asked, the dates are presumably being taken with a large dose of salt, or at least a significant degree of leeway.
