I based those numbers off the fact that the
HMS Aquitania had been refitted as a troop transport to carry 7,000 troops in Nov 1939. (

What really happened:
U-102 (VIIb) had been assigned to patrol AN29,
after Norway fell, so all I was encountering was German coastal traffic. Really quite boring. So i headed around the British isles and was operating off the Keltische See, and down around Biscay. Only encountered a couple small French merchants. Stopped in at Vigo, Spain to resupply at the
Bessel. After heading north again, back into Biscay, again only a few small French ships, I started back up around the isles. I was very disappointed I missed out on all the fun at Dunkirk.
While I was just south of Ireland, BDU started calling for a wolfpack to be formed off the Iberian Peninsula, in hopes to intercept some transport ships. I turned south at a decent speed. Just as I was clearing the continental shelf, sonar (due to the bad weather, we kept submerging) picked up a warship closing fast on me from the north. I dropped to scope depth and found the Hood and some escorts bearing down on me. I ended up getting off 2, 2 eel salvos, but only managed to hit the bow and stern, and she kept steaming on.
Still sailing south, I finally encountered the convoy. 8-10 LARGE transport ships, heavy tonnage all of them. I assumed the Hood was around here somewhere as an escort, too coincidental not to be, but I couldn't find anything more than 2 flower class escorts. It was a massacre. Only 1 of the first salvo hit the first ship (which sunk from the one hit), but apparently the second eel hit a ship in the second line. The second salvo obliterated the third ship. We had to use one of our 2 remaining eels to finish off the lucky hit, and the flowers were bearing down on us, so we slipped away to the South.
Then we picked up another warship closing from the south. Surprisingly, it was the Hood, barely able to keep up with the convoy from our previous damage. We fired our final torp into her, hitting her square midships, but she kept plowing on. Warrant officer Bernard suggested opening up on her with the deck gun. The final report states he "Erstickte an einer gabel".
It was great to go from a very disappointing double patrol to my best ever. 125k+ tons.
