Problems posting.
Bunji,
Sorry, I should have provided more details, I was trying to make my OP as brief and to the point as possible.
The "no third war" refers to the wars specifically led by Antiochus IV Epiphanes, the Seleucid king of Syria, against Egypt and do not include those fought by his predecessors.
Daniel accurately referred to two campaigns which Antiochus IV Epiphanes led against Egypt. Daniel then made an intelligent guess based on Antiochus IV Epiphanes' military successes and predicted that Antiochus IV Epiphanes would invade Egypt a third time, conquer it and revel in its riches. It is this third war that did not happen.
To your point about the total 6 wars between the Ptolemaic and Seleucid dynasties:
The following source compares actual history with the so-called "prophecies" in Daniel 11 regarding the wars between the dynasties. It provides a good comparison but doesn't state whether Daniel failed to mention any of the wars which actually occurred according to history. I will have to research that further:
