Raid Successful
The Orcs assisted Karl with escorting the varied assortment of slaves out of the inner city and through the nearly finished battle in the outer city, then past the gates to freedom.
The Elder Orcs looked impressed at the performance as they held off the remainder of the Giants so that the younger fighters could make their retreat.
The battle was a success by any measure, and though they hadn't completely eliminated the defenders, they had inflicted severe injuries on them, including their most defended members, and they were going to have time to retreat from the battle before the other Giants could arrive to support them.
That was the goal of the night raid, and the Giants' terrible night vision was working in the Orcs' favour, as the massive warriors wouldn't be able to even see where the Orcs went.
