Worm hole sequence question

[Dogboy]

If I am sending a fleet through a wormhole, does order matter? In particular, say there are enemy fighters and mines on the other side of the wormhole. If I send my warships in followed by mine sweepers, will the sweepers protect them from the mines? If not, won't the sweepers be killed by the fighters as they will momentarily be unprotected? Generally speaking, what is the best use of sequencing at wormholes?

Thanks!
