About the time that Colonel Kennelworth was transferred from Cincinnati to Boston, General Pearson had been sent to Cincinnati to operate the Tunnel machine from there. Immediately before the final attack on New York City, Supreme Commander Gordon ordered General Pearson to swing the Tunnel machine to the East and establish a Tunnel thru the Air between New York and Cincinnati, informing him that the expected final attack upon New York would come over the mountains of Pennsylvania and that this final attack would be from the West; that he wanted a Tunnel thru the Air at least 30 miles wide so that he could protect the Jersey shores and prevent the attack upon New York City. In a few minutes a test was made and the Tunnel was ready to receive the invading army of planes and airships. He knew that New York was now safe and awaited the final combined attack of the Enemy planes that would come across from St. Louis and Chicago to meet on the Western side of the Hudson River. About 12 o'clock he sighted the enemy planes across the Western coast of Jersey moving in triangle form, and knew that it was the combined forces with probably more than 50,000 planes ready for the final attack. Swiftly they approached, closer and closer. He played his powerful searchlight upon their glistening wings, until they were within 15 to 20 miles of New York. Fearing that they might start dropping bombs on Newark, Jersey City and the towns on the other side before attacking New York, he adjusted the Tunnel thru the Air until it was high enough to reach the enemy planes flying at the highest altitude; then turned to Colonel Edna Kennelworth and said: "Turn on the sleeping gas machine. The Tunnel is ready and as the aviators go to sleep, the machines will plunge into the Tunnel thru the Air and remain suspended without the planes being destroyed or the loss of any lives. This will be a silent, painless victory, but it will demonstrate our power to the enemy and the world."
