"Reach your gear" is the first mission objective in Sequence 2 / Memory 06: The Treasure Fleet
Here you meet Adewale and you both must escape
First you need to retrieve your gear. Since you are unarmed, fighting the enemy soldiers head on is a bad idea.
The best approach is to get close to a wall's corner to automatically hide behind it, like this:
You can perform stealth assassinations from there if the enemy comes near
Furthermore, you can whistle to grab the enemy's attention.
Kill each of the soldiers using this type of assassination, and you should be able to reach your gear which is on the table at the end.
