Ancients at Black Hills: Magnesia 190BC

Chris & I went to Black Hills to fight Magnesia 190BC using PeterC's troops & rules.
Jim: Roman & Pergumum.
Chris: Seleucids.

The Romans are on the right. Legionaries in the centre.  Bowmen & elephants on their left. Cavalry on the their right.
The Seleucids have their phalanx just left of their centre.  Cavalry & light infantry on their left.  Galacians & Argaraspids are on the right of the phalanx, then cavalry & elephants on the right flank.

The Romans made a general advance.  The Seleucids started moving their heavy cavalry from their right to their left.

The first clashes are cavalry on the right & some skirmishing in the centre.

The cavalry fight on the right is so far indecisive.
Legionaries have engaged the phalanx & Galacians in the centre.
On the left legionaries have driven back the light cavalry & engaged the elephants.

On the left the legionaries & Pergumese elephants have driven off the Seleucid elephants & light cavalry & broken the Argaraspids behind the Galacians.  Triari have wheeled to face the flank of the Galacians.   The phalanx has got the upper hand, but the legionaries are stubbornly hanging on.  The Seleuicid cavalry has also got on top, but has not yet broken through.

The Triari have charged into the flank of the Galacians.  The Legionaries & the Pergumese cavalry on the right are still holding on.

The Galacians have broken exposing the flank of the phalanx.

The Pergumese cavalry have finally broken on the right, but the winners have lost heavily & fall back behind their supports.

A fresh cohort hitting the flank of the phalanx has broken it.  Now with their right flank & centre both broken the Seleucids concede the battle & retreat.
The Seleucids erred in leaving their right too weak to resist the Roman attack.  The Romans broke that flank then rolled their army up from there.
