Holland Smith was born on April 20, 1882 in Hatchechubbee, Alabama to John V. Smith and his wife Cornelia Caroline McTyeire. He received a Bachelor of Science degree from Auburn University (then known as Alabama Polytechnic Institute) in 1901. He had already decided on a military career and had become first sergeant of a cavalry company in the Alabama National Guard. However, he obtained his Bachelor of Laws degree from the University of Alabama in 1903 and practiced law in Montgomery, Alabama for a year.
After the latter assignment, General Smith assumed command of the 1st Marine Brigade at Quantico, taking that unit to Guantanamo Bay, Cuba, for extended amphibious training in October 1940. In February 1941, when the brigade was redesignated the U.S. 1st Marine Division, he became that organization's first commander. He returned with the division to Quantico in April 1941, and in June of that year he was detached from it to take command of the organization that eventually became the Amphibious Force, Atlantic Fleet. Under this command, the 1st Marine Division and the 1st and 9th Army Divisions received their initial training in amphibious warfare. Moving to San Diego in August 1942, the general took command of the Amphibious Corps, Pacific Fleet, under which he completed the amphibious indoctrination of the 2d and 3d Marine Divisions before they went overseas, and the 7th Army Division and other units involved in the Aleutians operation. The Amphibious Corps, Pacific Fleet, was later redesignated the V Amphibious Corps, and in September 1943, as commander of that unit, General Smith arrived at Pearl Harbor to begin planning for the Gilbert Islands campaign. He continued to head the V Amphibious Corps until August 1944, when he was named Commanding General, Fleet Marine Force, Pacific, at Pearl Harbor. Subsequently, he commanded the Fleet Marine Force. In addition to that post, he commanded Task Force 56 in the Battle of Iwo Jima before returning to the United States in July 1945, to head the Marine Training and Replacement Command at Camp Pendleton, California. Holland was known for the quote "In our corps without responsibility and discipline we would not have won the Battle of Iwo Jima." U.S. Navy Admirals Raymond Spruance and Richmond Turner wanted General Smith to command the Okinawa invasion forces. They were overruled by CinCPac, Admiral Nimitz because General Smith had sacked a U.S. Army General, Ralph Smith, during the Saipan campaign, and justifiable animosity between senior U.S. Army staff existed towards General Smith due to his service chauvinism. U.S. Army General Simon Bolivar Buckner, Jr. was appointed to command the Okinawa invasion in his place. Coincidentally, General Roy Geiger USMC, was placed in command of Tenth Army in June, 1945 when General Buckner was killed in Action.

What were his duties there

Helloween are a German power metal band founded in 1984 in Hamburg, Northern Germany by members of bands Iron Fist and Gentry. Its first line-up consisted of singer and rhythm guitarist Kai Hansen, bass guitarist Markus Grosskopf, lead guitarist Michael Weikath, and drummer Ingo Schwichtenberg. After the release of a self-titled EP and their debut album Walls of Jericho in 1985, it expanded into a quintet with the addition of singer Michael Kiske, Hansen choosing to focus on guitar instead. Under this line-up, they released the Keeper of the Seven Keys albums (1987 and 1988), which established Helloween as a notable heavy metal band and led to the creation of the power metal subgenre.
The year 2000 saw the release of The Dark Ride, a more experimental and darker album than their previous releases. It came complete with downtuned guitars and a gruffer singing style from Deris. Immediately following the tour, Helloween parted ways with guitarist Roland Grapow and drummer Uli Kusch. One version of events states that Weikath, Deris, and Grosskopf felt that Kusch and Grapow, in particular, were spending more time on and paying more attention to their new side-project, Masterplan (Grapow's output on Helloween albums had dropped to barely one song per album by that point); since the others believed that Kusch and Grapow were not one hundred percent dedicated to Helloween, they were dismissed. They were replaced by guitarist Sascha Gerstner (ex-Freedom Call, Neumond) and drummer Mark Cross (ex-Metalium, Kingdom Come, At Vance, Firewind), culminating with the recording of another studio album, titled Rabbit Don't Come Easy, in 2003. The band met Sascha via a recommendation by producer Charlie Bauerfeind. According to Grosskopf, one day he was recording something with Freedom Call "and later on we called him up and he went to first meet Weiki because it was very important that Weiki finds a player that he can play with and also communicate and understand. [...] So we got him on the island where we recorded and let him hang out with us a little and then he decided 'Good, let's go'." Later in 2012, on an interview with Metal Shock Finland's Chief Editor, Mohsen Fayyazi, Roland stated: Cross could not finish the album due to mononucleosis, completing only two tracks; the drum tracks were completed by Motorhead's Mikkey Dee. Stefan Schwarzmann, former drummer of Running Wild and Accept would shortly thereafter take over the drumming duties. Despite a somewhat tepid response to the album, Helloween nonetheless completed a successful world tour, highlighted by the return of classic songs such as "Starlight", "Murderer", "Keeper of the Seven Keys" and "How Many Tears" to the setlist. Additionally, the band toured the United States for the first time since 1989, playing to sold-out crowds at nearly every venue.

Who were they replaced with?
guitarist Sascha Gerstner (ex-Freedom Call, Neumond) and drummer Mark Cross (ex-Metalium, Kingdom Come, At Vance, Firewind),
