Morgan Earp brought him to Tombstone—just in time for the gunfight.
On October 21, 1881, Wyatt Earp sends brother Morgan (photo) to Tucson to bring Doc Holliday back to Tombstone. Ostensibly, Doc is to calm Ike Clanton, who thinks Wyatt has revealed a secret political deal the pair had. Instead, Doc’s appearance only adds fuel to the fire, increasing tensions between the Earps and Cowboys. But Wyatt also knew he could trust Doc, and he may have wanted the dentist around, just in case violence broke out. It did—five days later, at the Tombstone street fight.
