I specifically targeted merchant only fleets and war fleets today. Merchant fleets usually surrendered within minutes due to lack of ordinance. In war fleets, even ships not carrying cargo (For some reason there is always one or two with decent cargo) have low shot counts and have run out of cannonballs or powder. There always seems to be one ship in a fleet that is well stocked, usually the one I have to chase down.
I had one battle that promised to be a challenge that ended up dissapointing. I joined a battle between British and Dutch forces while flying the british flag to find the following battle fleets:
Dutch: 2 MOW MM, 1 MOW, 2 Battleship MM
Britain: 1 MOW, 2 Galleon, 1 Frigate, 1 Brig
My Forces: 3 Super frigates, 1 heavy warship
I though "Wow this is gonna be a slug fest". Within 2 minutes the brig was done for as it sailed right at the dutch MOWs. I tried to skirt around the Dutch in an attempt to get my fleet to line up behind me but the dutch were upwind and closed fast. my fleet got caught and I thought I was going to lose a frigate. I should have lost a frigate. He was being shredded by a MOW and a battleship. Then both the MOW and the battleship just up and surrendered. Then a Dutch MOW MM was sunk. Then a British Galleon surrendered. The reamining Dutch MOW MM broke away and ran, so did the battleship. I ordered my intact Frigate and warship to pursue the battleship while I chased the MOW. The battleship surrendered, which seemed strange because by now there was no one near him. As soon as I cleared the pack of surrendered ships, the MOW surrendered.
Then for some strange reason the remaining British Galleon and MOW surrendered even though there was no enemy left to surrender to and the british frigate remained. After boarding the Dutch ships I realized they were all in good physical shape, still had good sails and hull, lots of crew. They just ran out of shot or powder. They had empty holds too, so cargo wasn't the problem. I can only speculate the British ships also ran out of ordinance. There were over 700 guns in this battle and only one ship sunk by them. Well at least I collected over 500k in gold off the captains coffers and traded a half dead Frigate for an almost pristine MOW.
This whole battle was over in under 15 mins.
I have set the surrend mod as follows: #define SURR_GLOBAL_SCL 0.3
Prior to setting it to 0.3, ships without ordinance would try to cut and run. At this setting, I find that ships surrender in a resonable or logical fashion. If they are suffering severe damage to sails, in combination with low or no ordinace, they surrender. If they still have shot, they usually have to be sunk or boarded even without sails.
Overall, I like the surrender mod at this setting. It is a good approximation of human thought. Some captains will surrender for the good of the crew, and others will fight to the last man. I would however like to know what to do to ensure they have sufficient ammo to do battle, even if it means less booty and less surrenders. Would that be the Ships.int file?
