On the table of Captain

In order to get this knowledge you have to play the full main questline, you cannot get it using the simplified questline that is available for a season char. When you get to the Heidel crossroad you have to select the LEFT option, which is called "The Lamenting Head of the League of Merchants" ( https://bdocodex.com/th/quest/21004/1/ ).

You then continue to play through the questline all the way until you get to the category "[I] Apparent Ambition". The fifth quest of that category is called "Delivery of the Operation Orders" ( https://bdocodex.com/th/quest/21013/4/ ). You can then interact with the Operation Orders on the table. This gives you the knowledge.
