It must be remembered that it's impossible to lose a time-active battle by dint of having too few troops (simply double any survivors' timelines back on themselves, although this is stretching the Homeworld's Protocols to breaking-point and is usually only done in a temporary basis) or by dint of insufficient pre-planning (since it's possible to pre-arrange tactics in local time). It's not even possible to lose a battle solely by dint of having lost it, as it can generally be fought again. It is, however, possible to have lost a battle — and for it to remain lost — if it remains unrecognized that a victory has in fact been achieved.
