Holland McTyeire "Howlin' Mad" Smith, KCB was a general in the United States Marine Corps during World War II. He is sometimes called the "father" of modern U.S. amphibious warfare. His nickname, "Howlin' Mad" Smith, had been given to him by his troops in the Dominican Republic in 1916.
On the eve of World War II, General Smith directed extensive Army, Navy, and Marine amphibious training, which was a major factor in successful U.S. landings in both the Atlantic and Pacific. He subsequently helped prepare U.S. Army and Canadian troops for the Kiska and Attu landings, then led the V Amphibious Corps in the assaults on the Gilbert Islands, the Marshall Islands, the island of Saipan, and Tinian in the Marianas.
During the Marianas operation, besides the V Amphibious Corps, he commanded all Expeditionary Troops, including those that recaptured Guam. He then served as the first Commanding General of Fleet Marine Force, Pacific, and headed Task Force 56 at Iwo Jima, which included all the assault troops in that battle.
