I bought the Wright book (let's hope). So I'm in with one of the two-stack armored cruisers. Of course if I can find one under a different flag, just to widen the research, but at the least the Chin 'en at Tsushima.
Edit: Yes, that's it. She was in the Third Squadron, Fifth Division at the Battle of the Japan Sea (Tsushima). Nuff said- she will join my Navy as a companion to the Mikasa.
Why is this important to me? Because this was the only decisive battleship engagement by steel navies.
