Nubian versus New Kingdom Egyptians and subsequent siege

I decided to try something almost contemporary to face Karl and his New Kingdom Egyptians.  I had to cobble the Nubians from my Carthaginian and Arabian armies and add in a DBA army that I had purchased but never used.  How would it all go?

Please note, for this post photos are mostly after each player's turn rather than pair of turns. This should provide a better feel for the action.

The Egyptian went up the Nile and invaded Nubia.

The Nubians were ready, deployed with a scrubby wood on their left

and some broken ground in the centre.

The Nubian wings fly forward

as the Egyptian chariots start to roll.

Nubian skirmishers run forward,

while their archers start shooting.

But once they get in range the Egyptian chariots have significant missile fire power.

The chariots mostly annihilate the Nubian archers.

But there are plenty of Nubians and their arrows continue to rain down on the Egyptian chariots.

In the centre the Nubian warriors are now with strike range.

The charge by the Nubian warriors cleared away the Egyptian archers, 

but was not able to prevail against the Egyptian foot.

The Egyptian chariots are now faced with redeploying while avoid being shot at.

A mighty charge by the Nubian warriors lead by their nobles scores a massive set of hits.

But hits alone do not do it.

The Egyptians reel back, 

but are not broken.

The Egyptian chariots are trying to get back into action.

However, the Egyptian foot must be feeling a bit abandoned.

Nubian archery decimates the Egyptian chariots

And the Egyptian morale collapses.

 Subsequent Siege

The Egyptians flee until they find refuge in a Stronghold on the Nile.  The Nubians pursue.

The Egyptian force is just 3 units with 3 steps, 7 manpower and 10 combat strength.

The Nubians have 8 units, 15 steps, 18 manpower and 20 combat strength.

They can easily lay siege but being on the Nile the Egyptians have the benefit of a port and are therefore not blockaded.  The Stronghold has a Resistance Factor of 7 and would resist any immediate call for surrender.

The Nubians start by filling in the moat, reducing the RF to 6.  They then deploy catapults further reducing the RF to 5.  Thinking they will get the Egyptians to surrender they supply lavish gifts, but the Egyptians can see bad omens if they accept and refuse to surrender.

At this stage the Nubians have run out of playable options and call upon the Fortunes of War, only to find a traitor in their ranks and the RF raised to 7.

But things get worse as an epidemic breaks out in their camp.  They still have 8 units, but now only 9 steps, 10 manpower and 12 combat strength.  The epidemic spreads to the Stronghold, but has lost it virulence and with the Egyptian washing of hands policy, has no effect on the defenders.

The Nubians continue to call upon the Fortunes of War only this time to find their supplies are running low which sees their force drop to 6 units, 7 steps, 8 manpower and 10 combat strength.  They might still have a significant force, but its strength has been halved. The RF has risen to 8.

However, the Fortunes of War start to smile upon them. They construct a siege tower which brings the RF down to 6. And then another siege tower is constructed, and the RF falls to 4.  Finally ladders and mantlets are deployed causing the RF to drop to a low of 3.  In desperation they would try an assault, but the Nubian combat strength, after adjustment for the RF, prohibits such a venture and the siege fails and the Nubians withdraw.
