In 1983 , the American journalist Daniel P. Mannix released an edited version of the autobiography of his father , Rear Admiral Daniel P Mannix the 3rd . The book , called '' The Old Navy : The Glorious Heritage of the U.S. Navy , Recounted through the Journals of an American Patriot '' , included the following paragraph : Vic Hurley , an American author who was a member of the Philippine Constabulary , wrote the book Jungle Patrol in 1938 , arguing that Colonel Alexander Rodgers of the 6th Cavalry Regiment ( brother of Thomas S. Rodgers ) had implemented the strategy of mass graves and pig entrails : After the September 11 attacks on the United States , a number of American urban legends began circulating that John J. Pershing had ordered the summary execution of captured enemies using bullets laced with pig blood , and whose bodies were placed in a mass grave filled with pig entrails . Dr. Frank E. Vandiver , professor of history at Texas A&M University and author of '' Black Jack : The Life and Times of John J. Pershing '' said about the burial of Juramentados with pig remains that he never found any indication that it was true in extensive research on his Moro experiences , and that such an event would be out of keeping with Pershing 's character . Rather , most sources indicate the idea of using pigs was suggested to Pershing but he rejected it
