Father Abraham

Head back to the marker labeled 'L' on the map and ride with Luisa Fortuna on the carriage.

Arrive at the bridge where you will set up an explosive ambush for an impending convoy.

To maximize the convoy's destruction, spread the dynamite placements effectively. The convoy will approach from your left, so focus your dynamite line from that direction.

Place your last stick of dynamite close to the bridge.

Run up the hill towards Luisa and the detonator.

You will need to 'prime' the charges before detonating them. The key is to prime the charge closest to the bridge first.

Detonate the dynamite, aiming to have the majority of the convoy already over the other dynamite sticks when the right-most charge explodes.

Quickly prime and detonate the remaining charges from right to left to take out more of the convoy.

Mop up any remaining stragglers with your rifle from your position on the hill.
