How to unlock the Demolition achievement in The Banner Saga 2 - Definitive Guide
Chapter 13 has two sections where you can destroy around 15-20 barricades, the first is on the Road to Old Ford, here you will battle Dredge, you can either fight them directly or behind you there is ice blocking you in, make sure you destroy all Ice barriers.
The second is when you reach OLD Ford you will be asked whether you want fighters or barricades, in order to select barricades you must select the Houses option on the camp site.
Barricades are a new feature in BS2. These are items on the battlefield that will impede your movement, but they can be destroyed by a direct attack to allow you to continue on. When you are on a battlefield with a few of them, don't go out of your way to attack them until there is one enemy left. You will enter Pillage mode at this time and get to attack multiple times before the last enemy, allowing you to use a few characters to target the barricades before finishing him off.
The initial battle where these are introduced has more than 20 of them, and there is a mandatory battle later in the game where you are required to destroy about 10 or so. If you clear both of these boards completely, that's all you need. However, if you do need more to destroy, Eyvind will learn an ability called "Troll Stones" that will raise a barrier for one round. You can use this, then attack it with another character before his turn comes back around.
