Having won the race to the bridge over the Shenandoah at Port Republic, Jackson left Ewell's division at Cross Keys to delay Frémont's pursuing divisions while he engaged Shields attacking from the north east. Shields' men fought well and tenaciously against psychologically as well as numerically superior troops, and although numbers told in the end, Jackson's 'foot cavalry' were too exhausted to turn round and do the same to Frémont's. They took the sensible option and withdrew through the Blue Ridge.
Jackson's Valley campaign remains a text-book example of using local knowledge, terrain and mobility as well as bold action, to occupy a much larger number of enemy troops. Jackson's 17,000 had kept 60,000 Union soldiers busy and disrupted Union strategy severely for that summer.
