Halydin will need to track the prints for a while to get a feel for how fast they are moving. he is aware that unless they brought two spare wolves (for the daughter and whoever's wolf was shot) some of them are traveling double and will thus be slowed down. If they have a long way to go, they will not neccassarily be pushing their mounts as well. Catching them is a possibility, though getting ahead of them poses some logistical problems.
I will presume that one of you goes to the prior meeting point and meets up with the now mounted dwarf and half orc, and that the others begin tracking, leaving occassional signs.
The five wolves have left a fairly clear trail, and Halydin does get the impression that two or more are riding heavy. After about an hour of movement through the woods, you find something you didin't expect - signs of a temporary camp, including an area where a tent of some sort was apparently set up. There is a pile of soft boughs aoung the tent stake holes. There is no sign of a campfire, but some wax is on the ground a little ways from the tent site where many feet (not paws) were gathered around.
It is while you are observing this area that your mounted compatriots catch up with you.
