But it was clearly a major reason and probably decisive, since the fragment also makes clear that Perdiccas immediately started the army on the journey to Egypt at precisely the point in time when the loss of the body was confirmed to him.
There clearly is no contortion you won't endure to defend an incorrect stance. Your original claim was that
"Ptolemy's seizure of the corpse was influential in deciding Perdiccas to attack Ptolemy rather than defend Ionia against Antipater". Thus Perdiccas, because the body had been stolen, decided not to defend the Hellespont. This is incorrect. Diodorus (18.25.6) plainly places the council which made this decision during the winter of 321/20. The body is stolen in the spring of
the following year. It thus can have had no bearing on whether Perdiccas marched on Macedonia or Egypt for the decision had been made. Justin too (13.6.10-13) associates this decision with the exact same events as Diodorus (likely working from the same source) though he does not even mention the body snatch.
Your reliance upon Photius' summary of Arrian and the palimpsest is increasingly desperate. We have no idea what preceded the first words we have; none whatsoever. There is no firm timing indicated. The only rock solid evidence is that the seizing of the corpse
confirmed Perdiccas' in a decision he'd already made ("made him even more determined" or "Then, even more"). This is about as plain as it gets and your refusal to see it can only be considered willful. It is clear as a bell that the seizure of the corpse played no part in the decision of Perdiccas and his philoi to march against Egypt firts rather than Macedonia. Justin's strategic reasons ("while they were gone into Macedonia, Asia should be seized by Ptolemy") are absolutely practical and there is no reason to ignore them (or summarise them out as Diodorus seems to have).
Quod erat demonstrandum.
Taphoi wrote:The obvious reason why Perdiccas changed his mind about allowing the corpse to be sent to Egypt would be that Olympias demanded the return of her son's body. Perdiccas needed her support.
That can only be speculation. The scenario is a possibility and Justin's remarks ("where Olympias, the mother of Alexander, was, who would be no small support to their party" 13.6.11) could be seen as some support. Just as likely is that Perdiccas, had he decided to march on Macedonia rather than Egypt, will have done so as husband of Cleopatra (a marriage he clearly intended) and with the dead king's corpse for burial. Olympias' support plays just as much a role in that scenario. He will have done so in any case had he succeeded in Egypt.

Yes Perdiccas' authority as
epimeleten de tes basileias, or regent, had been challenged as Perdiccas wanted the body to go to Macedonia under his care. This challenge to Perdiccas' authority - at the risk of repeating the clearly obvious - came after the decision to deal with Egypt first. Other challenges to Perdiccas' authority were the trigger for that decision: the annexation of Cyrene, the murder of Perdiccas' hyparch Cleomenes and, certainly, the marriage alliance with Antipater which sealed the "anti-Perdiccan" triumvirate with Craterus. These events saw Perdiccas facing two threats: invasion from Macedonia and Ptolemy in his rear. The council with his philoi, over winter 321/20, was called to decide which to deal with first. It chose Egypt. The body snatch was yet to occur.
