Men Of War: Red Tide mission question

[colletorww2]

I am on the campaign called "Company Of Heroes" and on the first mission there, i defended the hell out of that position and when i have hunted down and killed the last german soldiers there i realise that nothing is happening.

There are no enemies left, but nothing happens, it could be that i did not defend the building at the pier, but it says that if you are pushed back from that position, you are supposed to defend the drop-off point. I had all my defence there and i finally made it after the third try, but nothing happens.

Could anyone please help me?

Cheers, Colletorww2
