Not that it didn’t have bigger problems. Pompey the Great, thinking the civil war was over, failed to capitalize on his victory at the Battle of Dyrrhachium, allowing Julius Caesar all the time he needed to regroup so they could meet again at the Battle of Pharsalus in August of 48 BC.
Pompey did not win the Battle of Pharsalus.
After his crushing defeat, he retreated to Egypt, thinking he could get troops and money by picking a side in the ongoing incestuous power struggle between Cleopatra and her brother-husband, one of the last of the Ptolemaic kings. He picked the wrong side, and the Egyptians sent his severed head to Caesar, hoping that he would pick a side in the ongoing incestuous power struggle between Cleopatra and her brother-husband.
Julius Caesar would indeed pick a side, but that is a trainwreck for later.
He took some time off, managed to recover his mutinying legions, and headed for a final showdown in Africa.
