Acquire information about the Dagger
During the cutscene, the contact will then tell you that some items are at the bottom of the shipwreck and you have to get there before the Dagger arrives.
Get to the location shown in the map below.
You can grab a boat at the coastline and row all the way there.
Do note that there are a couple of sharks underwater. You may want to kill some of them first using your bow, before you dive in.
Next, dive into the water and get to the bottom. You will see a chest with glowing purple bubbles.
Loot the chest and you will literally acquire a dagger.

Kill the thugs

You should receive gauntlets and a breastplate as rewards.
