That leads to another problem. With three SDs and all those TIEs, the Imps have no real reason to send more than one SD after our bait, or really even one at all. Our faked run could draw a few TIEs, but we have no assurance we'd be importance enough for a SD.
I assume that the SDs are holding a position above the city, Ush? Would it be possible to send an easily incercepted transmission giving the coordinates of the freighters' entry point as somewhere on the other side of the planet? Would that even be worthwhile?
That depends on how much the Imperials have to enforce a blockade.
But in order to save you guys time, I will preview and tell you that they got the genuine cargo manifest, so even if you bring the blockade down it is still going to be up at the time the freighters come, so unless you managae to spctacularly deceive everyone about what is on the ships, and what they are for (unlikely) then no, the bloackade will have to be run.
