What, then, to make of Diodorus, 17.65.1?
After the king had marched out of Babylon and while he was still on the road, there came to him, sent by Antipater, five hundred Macedonian cavalry and six thousand infantry, six hundred Thracian cavalry and three thousand five hundred Trallians, and from the Peloponnese four thousand infantry and little less than a thousand cavalry.1 From Macedonia also came fifty sons of the king's Friends sent by their fathers to serve as bodyguards.
It would appear the confusion extends to the
pages as well. As Heckel observes, the ancient hisorians of Alexander applied the term somatophylakes to the Pages, the agema of the hypaspists and the bodyguard of the "seven".
Taphoi wrote:It amounts to special pleading to read across Arrian’s usage to re-interpret Diodorus’ statement that Hephaistion was chief of the Bodyguards, when there is no reason to disbelieve that the usual Vulgate meaning is intended.
It also seems that Arrian loosely used somatophylakes to refer to the entire corps of the hypaspists and not just one squadron among them. C. Bradford Welles thought this a sufficient reason to discount the possibility that Hephaistion commanded hypaspists at Gaugamela, because Nicanor seems to have commanded the hypaspists there.
I do not think it amounts to "special pleading". The terminology in Arrian is confused. Diodorus claims Hephaestion “commanded” the body guards. I can think of nowhere else that a “commander” of the “seven” is attested. That is not to say that it might not be but I can’t think of it.
Taphoi wrote:It is certainly untrue that the command of a squadron of hypaspists is in any way as significant as command of the Seven (later Eight) Bodyguards. These men became the top staff officers of Alexander’s regime. It is tantamount to Hephaistion having already been Alexander’s deputy at Gaugamela
Nicanor is indeed referred to as being in command of the hypaspists. In exactly the same way that Philotas is in command of the Companion Cavalry. It is Cleitus, though, who is in command of the
ile basilike or “Royal” squadron of that cavalry.
Hephaestion, if he is commanding the Agema of the Hypaspists, is commanding a prestigious unit: the king’s foot guard. Judging by Arrian’s claim that some 700 of the agema crossed the Hydaspes with him, it was a sizeable unit as well. This unit, made up of the sons of the Macedonian nobility, was no insignificant command. As I pointed out, Seleucus commands it later in the campaign after Hephaestion is promoted to a commander of the Companion Cavalry. It is not unlikely that he did from horseback.
And yes, it is difficult to see the hypaspists keeping up with their king. They may well have caught up to the melee, indeed they would have to, as it was their remit to keep contact with the king. It is why they are stationed in close proximity and why the gap will have opened at both Gaugamela and Issus as they followed their duty and their king.
The hypaspists were the corps d‘elite of the infantry and the Royal hypaspists were the noble nucleus of that elite. Later, after Alexander’s death, it is well attested that the regular hypaspists – the Argyraspids – scorned or resisted those who attempted to impose their authority upon them as these individuals were in no way Alexander or Philip. They did, though, still respond to the directions of the Argaed house when they took up service under Eumenes’ in the Kings’ names.
