If you got a B-rank then it cannot have been just the sub and Re alive. Two ships alive in the enemy fleet is always an A-rank. (If you don't sink any of your own ships anyway.)

My hypothesis would be that you didn't actually kill the Wo flag, that it had just a few hp left. That's consistent with both the B-rank and the gauge not progressing. You really only need to sink the flagship for that, just like any other EO.
