The message that Khao'khen sent to General Snowe was carried by a Verakh under a white flag, which was the second time in the campaign that the Horde had initiated formal communication under that protocol, the first being the delegation to Greywater that had returned with a crossbow bolt as its answer.
The Verakh found Snowe's advance guard four miles north of the corridor entrance, the Threian vanguard's pace slowing as it absorbed Thaddeus's withdrawing force and the colonel's report of the corridor's loss.
The white flag was respected without hesitation, because whatever Snowe's other qualities, he was a soldier who observed the conventions that made warfare between professional forces something different from the unstructured slaughter that the absence of those conventions produced.
