My adviser's brilliance crushed the Blackbeard's fleet, and we held a banquet to celebrate. The banquet was short lived however, for a arrow flew right past me and struck a pillar. Attached was a message from Blackbeard. It reads
Arrr, how dare you attack me branch fleet while I was out swashbucklin'. By the name of meself, I will send you to Davy Jones' locker.
I realized right away that I had made an error in my previous attack. It was indeed too little to be called the Blackbeard Grand Fleet.
Quickly, I dismissed the banquet and summoned my military adviser to discuss how we should prepare. He advised that we strike them in the high sea instead, as fighting at home would potentially put all the citizens in danger. He further said that Blackbeard would most likely sail directly from where the previous engagement was, so we should prepare to scout in that general direction right away.
Thus once again, scouts were sent out. But by the time we received a message, it was near nightfall. It read
We have found a fleet wearing Blackbeard's Jolly Roger. However, because it is dark, I don't see Blackbeard anywhere. To make things worse, the fog makes it hard to pinpoint the location of their ship, so I can only attach a map with how many ship pieces there are on each row and column. Based on my first speculation, there's again 1 flagship, 2 frigates, 3 corvettes, and 4 patrol boats, and I do not believe they touch each other. Not even diagonally.

My adviser looked at the map for a few minutes, and said to me: this is most likely his vanguard fleet; we still need to crush them, but his main fleet should be not far behind, and I should send the scouts there instead. Then, he quickly disappeared into the operation room like before, leaving me pondering how he managed to find the ships using this map.
Can you guys help me figure out the enemy location again?
