In the end the S-boats were all sunk quite quickly (one by a German torpedo!), for the loss of only 1 Fairmile, so we allowed Mark to have two more in reserve, which turned the game around completely. We also sank both the reserve S-boats but not before they had sunk another Fairmile, two of the LCIs and one of the LCAs. When the bunker guns finished off the last LCI the Brits could no longer get enough troops onto the beach to achieve their victory conditions.
Just a few pictures.
The first successful torpedo hit for the Germans, unfortunately it was on an S-boat.
A second torpedo hit on the large LCI quickly sunk it.
Other games that evening:
And a Warhammer 40K game.
