plans for attacking the large northeastern cities such as Boston and New York. Reference to this discovery was published by Vagts in a 1940 article in Political Science Quarterly. A discovery of a similar recommendation from 1900 by Diederichs for an attack upon New England, based upon a study done in March 1899, was found by German military historian Walther Hubatsch. But in his 1958 book Der Admiralstab und die obersten Marinebehörden in Deutschland, 1848-1945, Hubatsch dismissed it as an example of routine thought exercise that exists in all naval planning staffs and not a mature plan. Next, historians John A. S. Grenville and George Berkeley Young found some plans. These were copies of some German Admiralty archives found in the Public Record Office in London and described some of the 1899 and 1903 plans in general terms; discussion of them was included in the authors' 1966 book Politics, Strategy, and American Diplomacy: Studies in Foreign Policy, 1873–1917. The full plans were finally discovered in 1970 at the German military archives in Freiburg by Holger H. Herwig, a doctoral student at the State University of New York at Stony Brook, during his research into Wilhelm-era Germany. The first publication of a study concerning the plans occurred later in 1970 in the German journal Militärgeschichtliche Mitteilungen in an article co-authored by Herwig and David F. Trask, a history professor at Stony Brook. The article was written in English but with quotations from documents left in German. Knowledge of the plans achieved much wider dissemination with a front-page story on their discovery in The New York Times in April 1971, featuring a summary of the findings and an interview with Herwig. Subsequently, the Herwig–Trask article was cited in dozens of books. Description and analysis of the plans were also included as part of Herwig's 1976 book, Politics of Frustration: The United States in German Naval Planning, 1889–1941, this time with all material in English. Despite this background, Germany's Die Zeit newspaper announced a "discovery" of the formal invasion plans on 8 May 2002. They too based this upon what they had found at the German military archives in Freiburg. Reporter Henning Seitz of Die Zeit wrote that the discovery "proves a continuity between the Kaiserreich and the Third Reich because the Nazis also wanted to risk a final fight for world domination with the United States forty years later."
