I had to go to a meeting early this morning down in the county seat. On my way I have to cross Blue Creek, called by the Indians "the blue water." It's a spring fed creek that runs strong all year. In 1855 there was the first "battle" between US troops and the Sioux on this creek. You can read about it by googling "the battle of Blue Water." It was actually an ambush of peaceful Indians by the Army, under the command of General Harney. Crazy Horse was there, as a lad of about 13. He had been hunting but arrived in time to see the results and help some of the wounded. You can see the cut-line of the creek bed in the foreground. At the time of the fight there would have been no trees here. The "battle" actually occurred a few miles downstream (to the right of the picture) but fleeing Indians came up this far and farther trying to escape from Harney's pursuing dragoons.
I have often wondered why it is that when the Indians win a battle it is called a massacre, and when the whites massacre some Indians it's called a battle. The answer is simple, of course: the winners write the histories.
