While the infantry was stationed in these woods, no time was lost. The men were given their final instructions in fighting Bosch. They were drilled hard every day and they became particularly efficient in the use of the bayonet, a weapon that in the hands of a Yank the Germans fear worse than anything else that I know of. Rifle practice, of course, could not be indulged in while in these woods, because the noise might attract German attention, but bayonet drills never ceased. Thorough drilling was also given in the use of machine guns. Men were instructed how to repair guns, were told what to do in case certain parts of the gun were injured, were shown how to take guns apart and put them together again, and before the end of the drilling, these men became as efficient in machine gun work as Fritz himself. The last step of the preparation was the bringing up of the tanks. These came up at night in great numbers. There were tanks of all kinds, from the huge British machines to the "petite" or little French tank. These were also camouflaged and concealed in the woods. After the tanks were brought up, their gunners were given a final thorough drilling in the use of their guns, their machines, etc. We had never before seen such a vast equipment of war material. It is difficult to express my feelings during the final days of this preparation. I knew that something of a gigantic nature had been planned and that the time was close at hand. I also knew that whatever it was it would surely succeed, for nothing could resist the combined force of all that preparation when the final word was given. I cannot but admit that enormous quantity of ammunition, the vast number of light and heavy guns, the thousands of men ready for the fray, caused me to feel a certain indescribable sadness, for I knew, that although success was sure to follow our drive, some of these brave boys were to pay the price with their lives. On September 11th, the boys were drilled for the last time. We were then required to strip our bodies of all our clothes and to smear ourselves with a salve. This was a preparation that was designed to protect the body from burns in case we encountered the deadly mustard gas. After dark and all during the night there was a steady stream of men going to their positions in the trenches. They knew that the time for the manoeuver to start was near, but whether it was to be 24 or 48 hours, they did not know. But we of the Flash Service did; we knew that at one minute past midnight on the morning of September 12th, the zero hour, the Germans were to be given their great surprise party, and we counted the minutes as they were ticked off the watch until that time arrived.
