Milk Cow v. Surface Ship Resupply

[rudewarrior]

IRL, correct me if I'm wrong, but when a U-boat docked with a U-tanker, generally what would happen is:

1. The resupply was done as quickly as possible, weather permitting.

2. The U-boat would get some fuel resupplied.

3. The U-boat would get ~1-4 air torpedoes, depending on availability.

What are the corresponding results for a surface ship resupply?

I know that the crew would get invited on to chow down and get some home town cooking (like in Das Boot), but what about the torpedoes and the fuel?

Did they get fuel, and if so how much? Did they get torpedoes also?

Any references anyone could point to would be much appreciated.
