One of the fastest ways to stock up on resources in Assassin’s Creed is to plunder a warehouse, which also helps you to upgrade the Jackdaw and supplies for Kenway’s fleet missions. You need the resources. But going guns blazing will send a guard to ring the bell, and that will cut the profits in half.
To maximize the profit, going stealth is the only option. This guide will help you infiltrate the plantation and get the loot key undetected, and empty the warehouse without raising any alarm.
Location of the warehouse
It is located near Havana, marked on the map, as shown in the image below.

Note: remaining in a low crouch for the entirety of this quest to avoid detection.
Begin at the Dockyard, turning slightly left, and advance until you reach a small grassy field. Then turn slightly right, cross the mud walkway, and reach a massive rock, as shown in the image below.


Once you reach the massive rock in front of the warehouse, before you can plunder the warehouse, you need to acquire the key. Look to your right at the nearby watch tower. Secure it, and look for the small pond where two guards are standing, as shown in the image below.


Securing the watch tower will help in locating the pond and being undetected by the sniper.

Move towards the pond to eavesdrop on their conversation, which reveals the key location on the opposite side of the water, marked on the image below.


Silently neutralize the guards standing in your path before crossing the pond to the other side, loot the key from the dead guard’s body, and head back to the warehouse to claim your treasure.
