Klm Surface Mission #4

It seems no matter what I try, I get sunk every time. I've tried all of the hints previously posted. I've turned 180 degrees, I've turned 180 and then 90 degrees north or south, I've headed right at them, I've fired torpedoes every once in a while, and the best that I can do is sink about three before going under.

Previously, someone suggested putting the 4" on "Defend Deck Guns". How do you do this? Maybe this will help me a bit.

If you are using a microphone simply yell "defend deckguns"

if no microphone click and open the Big Tac screen and click on the icon that illustrates the deckgun.

Just keep trying. I took me about 5 trys.

HINT: Try to play it when sea is calm. So, if the sea is stormy re-load the mission again and again until is calm. It's easier for your gunners to aim.
