On Orberg LLPSI Cap XL scribitur:

At pius Aeneas, quamquam amicam dolentem solari cupit, tamen iussa deorum exsequitur classemque revisit. Ibi vero Troiani studiose laborant, robur e silvis conferunt et iam de toto litore naves celsas deducunt. Novae carinae natant, socii tota ex urbe concurrunt.

Quo tum dolore Dido afficiebatur talia cernens!

Quo = itaque…igitur…ergo…?

Quo is abl. sing. of the interrogative pronominal adj. qui, “what?”, agreeing with dolore. It’s used here in an exclamation. “With what grief was Dido then afflicted when she observed such things!”
