Unless the code has recently changed, yeah, yeah, delay arrival doesn't work over sea routes.
Nothing like 30+ letters per turn trying to organize the invasion of Nbasah (twice). Hellish, just hellish, but damn did it feel good when everyone arrived on time. The winter assault was the worst, it was five straight turns of correspondance.
Marine assaults are supposed to be difficult though, and the real problem is that there is an increaseed variance factor on sea travel (+/- about 40%).
There are so many inrigues running both ways that everyone knows that's how this sort of war ends. Hey, I'm now three for three in running rebellions, so maybe I can just replace some of those southern kings with more tractable lords.
