Oriamendi East – A Shako Scenario

Boina is the name I’ve given my Shako variant for the First Carlist War. This is a Boina scenario for the eastern part of the Battle of Oriameni (or Battle of Hernani) 16 Mar 1837.

Historical Situation

Setting: Hernani, Biscay, Spain; 16 Mar 1837

From 10-17 Mar 1837 the Cristinos attempted a grand three-pronged attack on the Carlist Army of the North. The British general De Lacy Evans advanced from the fortress of San Sebastián, Espartero from Bilbao, and Saarsfield from Vitoria. The Anglo-Spanish of De Lacy Evans were the only force which pushed their advance with determination. On 10 Mar Evans crossed onto the right bank of the Urumea River by a bridge of boats, and took the Carlist trenches and barricades on the hills of Ametzagaña (about 3km from San Sebastián) and those in front of the nearby position of Alza. In pouring rain on 12 Mar Evans ferried Chichester’s Brigade across the Urumea to capture the ruined village of Loyola. On 13 Mar British sappers and miners built a second bridge of boats across the Urumea, thus securing the British communications. Evans ferried his forces across, less a battery on Ametzagaña, and one and a half battalions split between Ametzagaña and Passajes. Heavy rain prevented further advances over the next two days. On 15 Mar Evans attacked the Oriamendi Ridge. By evening the Anglo-Spanish force was in possession and looked over the town of Hernani. On the morning of 16 Mar the British force was dispersed and their brigades intermingled, having failed to reorganise after the previous days battle. Nonetheless, success looked assured against the numerically inferior Carlists.

This scenario just focuses on the action on the eastern flank between Oriamendi Hill and Hernani.

Map produced in CC2

This scenario just focuses on the action on the eastern flank between Oriamendi Hill and Hernani. The Oriamendi Ridge was steep and craggy with bushes for cover.

The map is for my dining room table, i.e. 50″ x 30″. Map scale is nominally 600 m to 12″ on the table.

Key features are:

  • The town of Hernani – four sectors.
  • A redoubt: Fuerte O’Donnell on Oriamendi Hill
  • The entire area covered by Oriamendi Ridge, including Bertizaran and Oriamendi Hill.
  • The River Urumea is only fordable at the marked ford.
