The Carlists fuelled by local knowledge have the initiative, however communication of orders have been an issue (queue failed order rolls). The Isabelinos force also making for the pass has suffered similar problems but were nearer to start with which negated their surprise and resulting chaotic response that a Carlist force was nearer to reaching it than thought.
By the time the Carlist force arrived the Isabelinos were already deployed across the entrance to the pass and ready to repel any Carlist attack. The Carlist commander decided that the fervour of the troops under his command would carry the the day pressed on to attack.
Continued fire from the rocket battery breaks the will of the Carlist cavalry to continue the fight.
The right flank defensive infantry line anchored on the rough terrain continues to disorder the advancing Carlist forces. While on their flank the unopposed cavalry threaten any advance from the Carlist forces onto their left.
Things are not going well on the Carlist right, a battalion of volunteers is surprised and broken by the Auxiliary Legion lancers so the division on the left cannot expect any support from that quarter.
As dusk falls the Isabelinos hold the entrance to the pass, battered by poor coordination and the constant disordering fire from Isabelino musketry the Carlists withdraw into the shadows of the sierra.
Until next time may all your dice roll high where needed and of course KBO.
