Adobe Walls shares many similarities with Little Bighorn. The battle features a famous US leader in Kit Carson, attacking a large Indian camp along a river with a much smaller US force. He is also temporarily separated from the pack train, and the size of the Indian force was greatly underestimated. Adobe Walls adds a new weapon to the series, the Mountain Howitzer. Although short in range it was a very powerful weapon and it had a huge psychological impact on the Indian warriors who faced it.
