Interesting that according to this document the 94 boat towed the 3 boat. If the 94 boat had this kind of battle damage, I would have expected one of the other undamaged boats to do the towing. An Thoi was fairly far away (50+ miles).
There is no doubt that PCF 94 didn't suffer any damage in the mine incident. Unless the windows were blown out in the rice incident, I don't think there was any damage. If there was, you can be sure it would have been included in the bronze star citiation.
