Their accounts are the reason why its been confirmed that indeed Alexander was handed his arse on platter by ancient Pakistanis. Too many inconsistencies and no non Greek sources like they were there in his earlier exploits in Persia and lands before that. I have already explained to you, majority of accounts mentioned by greeks are myths, self glorification and preservation of the image that build around the "undefeated" Alexander the "great".
It is merely amusing and nothing more to see that the lack of non-Greek sources leads to a conclusion that the missing evidence proves your illusory case. You say that the majority of accounts mentioned by the Greeks are this, that or the other; when did the Greeks monopolise the narration? It may, or may not, have come to your notice that there is a mix of Greek and non-Greek sources in these histories; you mention Curtius, Justin, Diodorus, Arrian and Plutarch; let's see what that gives us:
- Curtius: Quintus Curtius Rufus - Roman, probably 1st century, about 400 years after Alexander; only book was his book on Alexander, originally in ten books, but available in badly patched up form, in nine books, each of which was in further incomplete, damaged condition; to draw conclusions about Hydaspes and its aftermath from his account is to look at the blanks and fill them up with one's own imagination. Roughly an approximation of your approach. His sources are not clear; since he mentions Cleitarchus (an historian in the Macedonian camp), Ptolemy and Timagenes, there is some speculation that he may have used their eye-witness accounts, since lost.
- Justin: Marcus Junianus Justinus Frontinus - Roman, 2nd century (one analyst says 4th century) therefore either 500 or 700 years after Alexander; his book was an excerpt of another book, by Gnaeus Pompeius Trogus, an earlier historian, from whose work he made excerpts. Not very accurate excerpts; he used the opportunity to moralise, rather than sticking to an excerpt. The original was a history of the Macedonian kings, not of Alexander alone.
- Diodorus: Diodorus Siculus (of Sicily) - Greek, 1st century BC, some 200 years after Alexander. He wrote a history of the world in 40 'books' (chapters). The history of Alexander is in the sections (chapters) 7 to 17, of which only 11 to 17 survive; so we have most of Alexander's life and times contained in this surviving section. He used a number of sources.
- Arrian: Arrianos, Arrian of Nicomedia, Romanised as Lucus Flavius Arrianus - Greek, 2nd century (probably around the time of Justin, if the traditional thoughts about his dates are accepted). He was a military officer himself, and that makes his accounts of Alexander more attractive. Generally, historians have taken Arrian the most seriously of the whole lot. He wrote a most attractive collection of books: on Alexander, modelling it on the famous Anabasis of Xenophon; a work on India, based on Megasthenes and on Nearchos the sailor; on hunting dogs, specifically a type of hound, and its characteristics and uses; on cavalry training; on a campaign against the Alans, which he won with the two legions at his command, and in which he describes the post-battle exploitation to be used, in terms of how the Greeks had used it in their time. Used to be considered the best account surviving.
- Plutarch: Ploutarchos, Romanised as a Roman citizen to Lucius Mestrius Plutarchus - Greek, 1st century, around 400 years after Alexander. Probably the most anecdotal, and the least useful from the point of view of concrete fact and evidence.
Is the point clear? It was not the Greeks, it was a collection of sources on which these accounts rest. Of the set that are usually cited, three are Greek, all Romanised Greeks, meaning, no Greeks that were writing in times when Greek cities were independent; two are Roman.
The narrative that even though he won against Porus yet his army rebelled against Marching further east due to heavy toll taken in battle of hydespas and bigger enemies they had to face in their path is, frankly speaking hilarious. Then why head south down the Indus? Were there lesser enemies down south? Heading into uncharted territories when your men are refusing to go further east, what made south lesser of a challange, when he knew that towards west in texilla and bectria, the lands under his command and control, taking the path he came from was not followed. WHY???
If you read the accounts, the passages through the mountains were not simple; there was every reason to believe that by reaching the sea, the army would have a safe and assured passage back home. Before marching down, and actually encountering enemies that they did encounter, they had no idea that some of the biggest challenges were still ahead.
That they headed south willingly was precisely the reason that it becomes clear that Alexander's army was not disinclined to fight, was not defeated and discouraged, but were willing to march through the plains and get to the sea.
You may like to read The Anabasis, where, when the inland-bound Greeks finally saw the Black Sea from an elevation, they broke into shouts,"Thalassa! Thalassa!" It needs more than a querulous, skimpy knowledge of history, twisted to form a self-serving account, to understand this campaign or what happened. If you could break away from your strenuous effort to prove that the people in the location of the present Pakistani Punjab defeated the world-conquering army of their times, you might make better sense.
A school boy error by biggest general in history where he nearly lost all his soldiers eventually taking his journey south? No, these were the conditions imposed by Porus on defeated Alexender, in return for sparing his life and his army, they will help him to expand his Kingdom by merging the Taxilla which was then ruled by Ambi. After that, Porus not only retained his kingdom but expanded it, with path to taxilla back to Persia no longer available, Alexander has no choice but to head south down Indus towards Arabia sea to retreat back to Babylon.
This is what I meant by a querulous and skimpy knowledge of history. Look up the governance of the Taxila region after Alexander departed, down to the point where Seleukos explicitly handed over the territory to the Mauryas. Please do not hallucinate in a vacuum; if you at least hallucinate over existing facts, it is bearable. This wholesale wild imagination of a hypothetical alternative history is really alarming.
I have been to taxilla many times, there are touts near taxilla archeological sites who sell the "fake greek" coin that they claim are from the times when Alexander came in that part of Pakistan. No where else you see the relics of this "misadventure". Consistence with the facts and ground realities.
If you can tear yourself away from your personal voyage of discovery, we can discuss history. Where else do you expect to see the relics of this 'misadventure'? Do you think that because touts do not sell you fake coins elsewhere in the Indus that the passage of the army was imaginary? Are there any more 'facts' like that you would like us to suffer?
If you can somehow manage to stick your nose out of your white master arse crack, sniffing all that come from it and taking it as musk, maybe, just maybe you can start to think more rationally. Colonial scar run deep, you are a prefect specimen of this sorry state of mind.
Don't be coarse.
