This last remark referred to the decision General Lyle had formed of placing the river between his party and the Indians before daylight. He knew that the Indians of the Plains, like all others of their race, are extremely averse to undertaking anything of importance in the dark. He also knew that their favorite time for making an attack is when they can catch their enemy at a disadvantage, as would be the case while his wagons were crossing the river and his men and animals were struggling with its probable quicksands. Another serious consideration was that, during the summer season, all the rivers of the Plains are liable to sudden and tremendous freshets, that often render them impassable for days. Thus it was unwise to linger on the near bank of one that was fordable a moment longer than necessary. He had, therefore, decided to make the crossing of this stream that night, as quietly as possible, and as soon as darkness had set in. For this reason none of the baggage, except the mess-chests and a sack of corn, had been taken from the wagons, so that a start could be made at a few minutes' notice.
