Everything was quiet and no move or attack was made until December 7th, when the enemy held a council and decided that a gigantic attack on Detroit should be made; that they should concentrate a large part of their forces there; destroy the factories and take Detroit; then proceed to attack New York and the Eastern Coast. The plan was to make a daylight attack and, if possible, to surprise Supreme Commander Gordon. About 3 o'clock in the afternoon the enemy planes were seen approaching from the East and West. He saw that this was to be a gigantic attack because there was a larger number of planes than they had used at any time since the attack of Chicago. Before he could get the Tunnel machines in working order and establish a wider range in the Tunnel thru the Air, the enemy planes had begun dropping bombs on the outskirts of the city and had destroyed many of the smaller buildings. The United States planes were attacked and being unable to rise to the heights at which the enemy planes were flying, a great many of our planes went down, but in a few minutes the Tunnel thru the Air was in working order and the enemy planes began to be drawn into it. Within less than an hour more than 2500 planes had been captured. The loss of life around the city had been small because the bombs which had been dropped had not reached the thickly populated sections of the city and no plane had been able to reach the factories or business sections where the large buildings were. The Tunnel thru the Air was protecting and keeping them away from these sections. Canadian planes had come to the assistance of the United States on the Northern border and were patrolling the other side of the river and preventing the enemy from attacking from the North.
