1394
Dozens of heroes and a large military invasion were successful in defeating a large contingent of Bloods forces. This was his first significant loss in history and with this the tides of war have changed.
1395
After several missions into the Islands that once made up the Kingdom of Roldem, Blood's forces suffer a major defeat by a large group of adventurers and allied military forces. Freedom is won, and the rebuilding of the ravaged islands begins.
I think the large forces that were defeated in the first entry were the ones occupying Roldem in the second. I also believe the second date is the correct one, and the first leaves out what exactly was the great victory, so maybe the second was meant to be a correction?
If it was just a fondness for the wording of the first, you could just tweak the second a little to say something like, "The tides of war are changed, as after several missions into the Islands that once made up the Kingdom of Roldem, Blood's forces suffer their first major defeat in history by a large group of adventurers and allied military forces. Freedom is won, and the rebuilding of the ravaged islands begins."
