Hello to the forum.

I have a question about the TMB mines and I was hoping these could be answered here. How were these mines launched? I believe that up to three mines could be placed in a torpedo tube. This leads me to wonder:
- could the mines be launched individually or did all three have to be launched at once?
- If the mines could be launched individually, how were they launched? What was the actual mechanism for ejecting a single mine from a torpedo tube and leaving the other mines behind in the tube?
- Wouldn't the submarine be moving forward when the mine was launched? Wasn't there a danger of the submarine colliding with the mine after it was launched if the mine was launched from a forward torpedo tube? I do understand that the mines had a timing mechanism and were not armed until the submarine had left the area.

Any and all information on these questions would be appreciated.
