But Sisko did give his warning "less than an hour" (that is, more than a half) before firing the torpedoes, after which there was a cut for this entire "less than hour". I rather doubt Sisko spent all of that staying mysteriously mum; he might well have gotten the lowdown of his target in sufficient detail to optimize his attack pattern and whatnot.
