A fierce war between the Paiutes and the California militia follows, and the Paiutes seize Adam as hostage. Very impressive battle scenes in the this first mini-epic of the series. This episode did all it could to stage the real thing; 50 Indians were used and 50 cavalry actors and extras were used, and the production involved three days of shooting on location. This episode encompassed both the biggest cast and most costly stunts. This episode is based on the factual accounting that occured in May and June of 1860.

Of course, his family helps him during the last half hour, and it all turns out that someone we should not have suspected did all the murders, but that he actually wasn't trying to hit

In one scene, Adam is dressed in black for the first time. In another, Hoss, upon seeing Southern California for the first time, remarks, "It sure ain't never gonna amount to much". Later, Adam makes an amusing reference to the chow Joe says he was forced to eat in "The Last Hunt".
