That is indeed an excellent idea - but as for leaving it until the final battle, I'm not sure. If there
was more of an Umbarian fleet, there would be enough of them to cut off any escaping ships, thus rendering the point of it being as an escape somewhat useless. Unless that could be the final straw, showing the somewhat hopeless situation that the corsairs would then be in...
However. We could always bring back the Gree- sorry, the 'Wildfire of Umbar' (nice one, Anguirel

) for the last battle and have lots more deliciously pyro battleness with it. But for now, I like that idea for this battle - it allows swashbuckling, a chance for slave freeing (a few of them, anyway - and I really like the Ferethor-Curamir idea) and then a suitably, well, not
too unrealistic escape.
What say ye all? Shall we stick by that plan? I don't want to make a post until we sort out what we're doing, for fear of toe-treading...
