Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. IN this book I have endeavored to present the true facts, as far as they are known, concerning German sabotage in the United States during the period between the outbreak of the World War and the entrance of the United States into the war. I have concentrated principally on the Black Tom and Kingsland cases, as they were the most devastating acts committed and the only ones, with the exception of ah explosion in Tacoma Harbor, in which any attempt has been made to prove German complicity and to collect damages. Having assisted the American claimants in their investigations in connection With the Black Tom and Kingsland cases, I have known intimately many of the principal characters involved and have obtained from them their personal stories. Because of this connection, too, the voluminous records of these cases, consisting chiefly of exhibits, briefs, oral arguments before the Mixed Claims Commission, and reports of the various American investigators have been at my disposal.
