My Legacy alternator failed this afternoon and battery went flat - no warning light came on.

Could I have got home 10 miles using my seven and a half amp-hour jump starter battery if I still had original battery connected or would I have needed to disconnect original battery?

I think you could have made it a ways, not sure how far. If your battery was dead, then hooking up the jump starter battery and leaving the original battery connected would have drained the jump battery a bit faster because the jumper would have been trying to charge the original.
