at Little Bighorn twenty years prior. While McKinley urged patience and did not declare that Spain had caused the explosion, the deaths of hundreds of American sailors held the public's attention. McKinley asked Congress to appropriate $50 million for defense, and Congress unanimously obliged. Most American leaders believed that the cause of the explosion was unknown. Still, public attention was now riveted on the situation and Spain could not find a diplomatic solution to avoid war. Spain appealed to the European powers, most of whom advised it to accept U.S. conditions for Cuba in order to avoid war. Germany urged a united European stand against the United States but took no action. The U.S. Navy's investigation, made public on March 28, concluded that the ship's powder magazines were ignited when an external explosion was set off under the ship's hull. This report poured fuel on popular indignation in the U.S., making war virtually inevitable. Spain's investigation came to the opposite conclusion: the explosion originated within the ship. Other investigations in later years came to various contradictory conclusions, but had no bearing on the coming of the war. In 1974, Admiral Hyman George Rickover had his staff look at the documents and decided there was an internal explosion. A study commissioned by National Geographic magazine in 1999, using AME computer modeling, reported: "By examining the bottom plating of the ship and how it bent and folded, AME concluded that the destruction could have been caused by a mine." Declaring war After Maine was destroyed, New York City newspaper publishers Hearst and Pulitzer decided that the Spanish were to blame, and they publicized this theory as fact in their papers. Even prior to the explosion, both had published sensationalistic accounts of "atrocities" committed by the Spanish in Cuba; headlines such as "Spanish Murderers" were commonplace in their newspapers. Following the explosion, this tone escalated with the headline "Remember The Maine, To Hell with Spain!", quickly appearing. Their press exaggerated what was happening and how the Spanish were treating the Cuban prisoners. The stories were based on factual accounts, but most of the time, the articles that were published were embellished and written with incendiary language causing emotional and often heated responses among readers. A common myth falsely states that when illustrator Frederic Remington said there was no war brewing in Cuba, Hearst responded: "You furnish the pictures and I'll furnish the war."
