Tags: Military Structure.
In spring 1864 a series of blockhouses were built in Lawrence Kansas to provide defnsive structures in case of attack by Confederate guerrillas. On August 21 1863 Lawrence had been attacked by 400 guerrillas and Confederate Army recruits under the command of William C. Quantrill. Lawrence was caught virtually defenseless and much of the town was destroyed and about 180 men and boys were killed most of them defenseless.
