Fighting the Boche Underground

IT has been frequently suggested to me that I write of my experiences at the front. As one of the advance-guard of the American army who participated in the great struggle for freedom long before the United States espoused the cause of the Allies, I am more than willing to do this, owing to my strong desire that the public should know something of the constant fighting which is going on underneath as well as on the surface and above the ground of the trenches both in France and elsewhere, especially if, by so doing, I can help the people at large more fully to appreciate the importance of the work and the unflinching devotion of that branch of the army which but seldom finds itself singled out for the bestowal of special honors or for the expression of public approbation.
