Soldiers drive a covered wagon loaded with dynamite and gunpowder to the gates of an indian occupied fort. 2 small barrels are placed under the wagon another opened and a trail of gunpowder laid away from the wagon and lit. The barrels explode, the wagon starts burning then a large explosion as the wagon goes up. There's shots of indians riding away then one looking through the gates showing the wagon intact, with the barrels underneath and the fire out.
Over 50 wagons are seen in various long shots but when camped never many settlers are seen and when the train reaches the fort only 3 wagons are inside and none outside.
