On the outcome of the Battle of Saipain hung the fate of the Pacific War, if the Japanese were to lost this island then the Home Islands would finally be in range of serious American bombing. As the fanatical resistance of the Japanese was raised to fever pitch by the exhortations of the high command, whilst the Marines who had learnt hard lessons on assault landings knew that the capture of Saipan could shorten the war immeasurably; so was set one of the bloodiest battles of the entire Pacific Campaign. The Japanese fought with insane courage, leading to massed banzai charges and civilian suicides; matches by the gritty determination of the experienced Marines to conquer. Contains 103 photos and 24 maps and charts. “SAIPAN was one of the key operations in the Pacific War; key because it unlocked vast potentialities to the United States in projecting its might against the Japanese homeland; key because it opened the door of distance which had meant security to the Empire. Invasion of Saipan provided the supreme challenge in which the enemy was forced to select one of two alternatives: conserve his naval resources for a later decision, leaving uncontested this penetration of his inner defense; or lash out in a vicious, showdown fight. The fact that he chose the latter course, and suffered a resounding defeat, is now history. The conquest of Saipan was, among Pacific operations up to that time, the most clear-cut decisive triumph of combined arms of the United States over the Japanese. By June 1944, U. S. forces, long superior in quality of personnel and organization, were finally greatly superior in materiel with which to fight. Victory at Saipan made this apparent to all.”-C. B. CATES, GENERAL, U. S. MARINE CORPS., COMMANDANT OF THE MARINE CORPS.

"Breaching the Marianas" by John C. Chapin is a book about the WWII campaigns and Marine Corps history. The book gives a detailed account of what happened on the Mariana Islands of Saipan during the war. Excerpt: "Breaching the Marianas: The Battle for Saipan by Captain John C. Chapin, USMCR (Ret) It was a brutal day. At first light on 15 June 1944, the Navy fire support ships of the task force lying off Saipan Island increased their previous days' preparatory fires involving all calibers of weapons. At 0542, Vice Admiral Richmond Kelly Turner ordered, "Land the landing force." Around 0700, the landing ships, tank (LSTs) moved to within approximately 1,250 yards behind the line of departure. Troops in the LSTs began debarking from them in landing vehicles, tracked (LVTs). Control vessels containing Navy and Marine personnel with their radio gear took their positions displaying flags indicating which beach approaches they controlled."

“The narrative moves smoothly and crisply. There is effective treatment of strategy, preparations, and then the invasion and battle for Saipan itself.” —Spencer C. Tucker, author of American Revolution In June 1944 the attention of the nation was riveted on events unfolding in France. But in the Pacific, the Battle of Saipan was of extreme strategic importance. This is a gripping account of one of the most dramatic engagements of World War II. The conquest of Saipan and the neighboring island of Tinian was a turning point in the war in the Pacific as it made the American victory against Japan inevitable. Until this battle, the Japanese continued to believe that success in the war remained possible. While Japan had suffered serious setbacks as early as the Battle of Midway in 1942, Saipan was part of her inner defense line, so victory was essential. The American victory at Saipan forced Japan to begin considering the reality of defeat. For the Americans, the capture of Saipan meant secure air bases for the new B-29s that were now within striking distance of all Japanese cities, including Tokyo. “Harold Goldberg’s riveting story of this conflict brings the dead back to life by blending rigorous research with dramatic narratives by hundreds of survivors. He has written a superb account of a pivotal, little-known, and heart-breaking battle.” —Col. Joseph H. Alexander, USMC (ret.),author of Storm Landings “Using recent interviews he conducted with extant US veterans, [Goldberg] skillfully develops the soldiers’ view of the battle for Saipan in an engaging, clearly written and interesting volume.” —The Journal of Military History
