Depending on the date, they do pay visits to Lorient. I have been in port several times when they come over, bagged a few of them too.
I have noticed that the escort vessel for Lorient does run aground in the channel after he has led you out and returned up the channel. He gets up to the point where he would have to turn right towards the dock area and he turns left instead and runs aground and catches fire before completing the turn to go back down the channel.
