Reinforcement battles - to CTD or not to CTD

[Avicenna]

1) Factions - (Yours/Theirs) I am KH in all battles. The other side is one time both Makedon, other time both Ptolemaics. One time is both rebels.
2) Circumstances - AI army attacks mine, which is besieging an AI city. All three times.
3) Leaders - In the Makedonian time, the attacking army was led by a captain, and the reinforcements by the Makedonian faction leader. In the Ptolemaic battle, both captain. Eleutheroi attackers were led by a captain, reinforcements by family member.
4) Outcome - Makedonians had 2 tiny units remaining. Ptolemaics utterly crushed. Eleutheroi destroyed as well.
5) Positioning - Makedonian battle was at the edge of the Mytilene island, but no port or buildings. Ptolemaic was inland with nothing but woods. Eleutheroi was similarly nothing, but I could see Kydonia from the battlefield.
6) Version - EB Version (v.72, v.73a, v.74) .74
7) Screen shots - sorry
8) Save game - sorry

NOTES: all three were victories in case you missed it.

Makedonian, even though it was most recent, I can't remember. I'm pretty sure it was clear.
Ptolemaic was heroic.
Eleutheroi was clear.

EDIT: almost forgot. No CTD on all three occasions.

[pezhetairoi]

I'm Romani, playing against Makedon, assaulting Demetrias with a relief force just outside the city.

Leaders: My army has two family members (and 3 triarii, 3 hastati, 3 principes, 4 equites, 2 akontistai, 3 toxotai), the Mak relief force is captain-led (1 taxeis hoplitai, 1 peltastai, 1 thureophoroi) and the garrison of Demetrias is led by a family member (one hetairoi bodyguard, one thureophoroi)

Outcome: No Makedon survivors. I intercepted the relief force outside (i was attacking from the west, but shifted all operations to the north during deployment, placing my army between the relief and the city) and crushed it. Then I stormed the city, killed the family member who contested the breach, and annihilated the thureophoroi by luring them out of the square and charging them in rear with my equites.

EB version: 0.74

Screenshots: none, sorry
