It is very simple. I was discussing it with Karen yesterday, as i met her here in Athens. First of all, Alexander won, and there really aint no debate here. But if you are wondering if Philip had entrusted such a position to his son because he thought he could win, or because of a custom, i think the answer here is also simple. The battle at Chaeronea was of great importance. Philip wouldn't put Alexander against the sacred band unless he knew that he could win. Alexander had experienced generals by his side, but surely Philip also knew his son's tamperament and that the final word at this position would be Alexander's. So yes, he put Alexander there knowing that he would win. I think this should pretty much cover it.
I think that if the decision was based on ability, then Parmenion would have been a better choice. Or any other experienced Macedonian general. If it was a matter of established Macedonian custom, though, then I can accept that Philip would have had little choice in this matter. But if it was custom, I’d also point out that the decision would have said little about what Philip might have thought about Alexander’s ability. That is, then it would be wrong to argue that it was necessarily a sign of “great faith” in Alexander. If it was a old Macedonian custom, then it was just business as usual.

Don't fret it. I'd prefer to say direct rather than infected. What cloth are you cut from?
I must admit that I found it rather refreshing. And I think I have a good general idea of what kind of cloth you are cut from. One can count on you to put up a good fight, and I doubt you have a glass jaw. Still, I don’t like the idea of me insulting people I don’t even know over the internet, particularly over something so utterly unimportant as Alexander, or the reasons for why Philip let him command the left wing at Chaeronea. In my opinion, this subject is, in the grand scheme of things, about as important as knitting or stamp collecting. And I suspect that were we to meet in person, our discussions would probably be more civil. But then again, it could also end with broken bones and a trip to the hospital.
You will be very lucky to find it. Macedonian history - as far as intelligible/reliable sources (outside of some numismatics and archaeology) go is thin on the ground prior to Philip. We have references that are oblique in Thucydides, Herodotus and others but fleeting. Suffice to say those compiling "histories" did not have Macedonians on their radar if they did not relate to what they were covering. Hence we hear of Archelaus and Perdiccas II etc in Thucydides only in relation to Athens’ needs for timber and Sparta’s need to dislodge the Thraceward region.
What is safe to say is that the kings of those tribes which later comprised Macedonia (and Greater Macedonia) Illyria, Paeonia, Thrace etc will have had their own courts. They will have led their armed forces into battle and will have needed to win to retain their thrones. Their sons, were they to succeed them, will need to have done similar. It was no different in Lower Macedonia. This is not something Philip will have started and nor will it have been something Antigonus (and Seleucus afterward) simply decided was a “good thing”. It was how they thought. Antigonus – like Philip with Alexander – was grooming Demetrius as his successor. For that to occur, Demetrius had to show his stuff on the field.
Interestingly, in those two battles, much more than Macedonia and Greece were on the line; this was literally for Alexander’s Asian empire. Had Antigonus lost – and I’d argue that he should have, treachery notwithstanding – he’d have lost the lot to Eumenes.
I think it’s entirely possible that you’re right. It’s just that I also think that evidence should be the bottom line. In this case, for the reasons you mentioned, the evidence supporting the idea of a established Macedonian custom seem impossible to find. This could have been – not must, but could have - a custom established by Philip himself. But then again, it’s also entirely possible that it was established long before him.
I haven’t actually disagreed with most of what has been said in this thread. I agree with you that Alexander was being groomed to be king. I agree with Marcus that it was fortunate for Alexander that this happened, considering that Philip died only two years later. And I agree with Phoebus that it is wrong to make anachronistic judgments (and no, I don’t find it hard to understand). And I’m well aware that Macedonia was a warrior culture. I don’t agree with the “it worked, so it must have been the best decision” argument. And I do think that a supervised Alexander as commander, rather than Parmenion in the same position, without supervision, would have meant a weakness in the army. Apparently not a crucial one, but a weakness – comparatively speaking – nonetheless.
But above all, I just don’t think any of these arguments prove that this was an established custom, and that Philip had no real choice in the matter. And as I’m not convinced, I’m going to have to keep my reservations about this decision. I’m going to have to chose the, not so much “agree to disagree” option, as the option to keep my reservations, but continue to hold the door open for evidence that might convince me that this was an established Macedonian custom.
