No.. it can't be.

I guess you didn't have enough Thureophoroi or peltasts (to win the wall battle) and archers/slingers to kill the elephants from the safety of the walls.

Reconsider that statement when looking at the actual army composition of those Indos valley cities.... By the time those cities have sorted their recruitment out, then those armies are worthy of a human player. Actually it is one of the few areas where the slave AI does recruit some pretty nasty armies, armies I could've thought of myself for a highly effective campaign army.

This was the way I conquered these cities in my Baktrian campaign a couple a weeks before.
I used 2 units of thureophoroi and 2 units of peltasts to storm simultaneously the wall from different directions and killed the Indian longbowmen, having about 30-50% casualties. When the job was done, I sent on the walls 2 units of eastern slingers and 2 units of persian archers targeting the elephants. Slingshots and flaming arrows killed some of the elephants and made the rest mad, so they started moving around killing their own men. After the elephants where gone, I sent 2-3 phalanxes and my general to kill the rest (mainly Indian spearmen). I have to mention that I play without the battle time limit.
It was a great siege battle, I really enjoyed it.

When it comes to the city with the stone walls i just starve them out, fighting on walls is bad enough without those machete weilding devils around.
My glorious indo-hellenic army (4 indo-hellenic hoplitai, 2 indo-hellenic agema, 2 indo-hellenic peltasts, 4 indian longbows, 2 sereni) got really badly chewed up invading one of the other towns but that was due to me forgetting about the beefed up elephant stats.
"Ho there Demetrios! do not fret over those elephantoi one volley of our mighty javelins should send them to hades....err maybe two" (stamp.stamp.stamp.)

All I know is thank you for alliances. Right now everyone is a war with arche seleukeia. We are all allied against them, Pontos, Ptolemaioi, Hayasdan, Pahlava, and Saka which makes for some good allied battles. Pahlava has been deflecting most of the stack that come my way.

Hmmm. It's interesting that your allies are actually attacking your common enemy. That usually doesn't happen. But as soon as Parthia and the AS sign a ceasefire, crush the nomadic bastards.

It would depend greatly on the difficulty. On Very Hard and Hard that would be a difficult battle, although on Medium it should have been reasonably winnable. Indian longbows and elephants are especially dangerous, particularly defending walls. I would have starved them out.

lol again, Baktria does not have the luxury of time, (at least in my experience, the Saka rauka were constantly on my spine and Pahlava were after my throat, and the AS were at my belly) You gotta move quick or you wont have enough funding to secure more land, letalone defend.

Haha, i have taken the city. I decided to take a risk and leave just 3 Hellenic Medium phalanxes and 1 persian archer and a general in Baktra, just enough to cover all the entrances into the square. I then sent a stack of whatever I could muster including my new fraction leader who happened to be the son and brother of my old fraction leader and heir. I got to the city only to find two units of archers, I attacked the city and the walls were still not repaired so I kinda just walked in and killed everybody. On another note Baktra was sieged 4 turns when I left by a full stack of AS units I let them build there equipment and they attacked me 3192 against my 637 I sealed of any entrances to the square and all of them came right down one street where they could not diverge anywhere because it was one single street so I rushed one of my phalanx around and crushed them between two units. Not one escaped. I gained a heroic victory.
