When Gen. Ewing took over his command of the border, he set up a system where by each little town had a squadron or company of calvary to come to each other's aid from different directions if a town was attacked by guerrillias- thereby surrounding them. So the garrison that saw the guerrillias wouldn't have been big enough to attack them by themselves. They did inform the headquarters in Kansas City, but it was late at night and........ Why they didn't shadow the guerrillias.....
And Sen. Lane is partly responsible for the lack of defense of Lawrence. Normally, it was the governor of a state who authorized the raising and appointment of the unit and its officers. In Kansas, Sen. Lane was charged with this responsibility, and received the kick backs ( money and political pull) from suppliers and prospective officers. When the governor of Kansas requested more troops for protection, under the govenors control, Lane refussed to raise them as he wouldn't gain anything. It was perhaps one reason why, after the raid, he was so adamant in his procution of the raiders, so as to divert attention from his failure to increase the states protection.
And I do think Price was an "conditional unionist" prior to the St. Louis massacre, where the events there of changed his thinking.
And there was a Lawrence woman who was accused of providing pre-raid information to the guerrillias, but for some reason, I can't find the book I'm looking for.
