What led to the  Battle of Saipan?

It all started in December 1941, with the Central Pacific Campaign, one of the longest in World War II when Japan attacked Pearl Harbor and severely damaged the US Fleet. Soon after, Germany and Italy declared war on the US, from where started one of the darkest chapters of World History. ‘World War II was waged on land, on sea and in the air over several diverse theatres of operation for approximately six years’ as quoted by MPW Stone Secretary of the US Army.

The Battle of Saipan was just one of the series of the Pacific Campaign. How things got uglier and reached the beautiful Island is mentioned as follows.

  • Japan carried out a relentless attack, acquiring the US territories of Guam, Wake Island and the Philippines and also the British territories of Hong Kong, Malaya and Burma so that the Pacific Fleet does not interfere with the series of its conquests. 
  • Japan also threatened the American supply routes to Australia, which was supposed to be the ground for offensive action by the US.
  • The US and its allies in Australia and New Zealand began a counter attack across the Pacific, which came to be known as the Pacific Campaign. Japanese held territories were acquired by the allied forces, with a goal to secure airfields and supply bases that could serve as launching points for future attacks.
  • By 1944, the naval and aerial strikes by the US reduced the Japanese bases in the central Pacific (when the Marshal and Mariana chains were acquired by the allied forces).
  • The Mariana Archipelago, was a part of the Japanese Empire since 1914, and was mandated to Japan by the League of Nations in 1919. Saipan Island, the second largest island of the Mariana Archipelago was a valuable asset for the US, thus making it a target of the Allied Forces.

Causes which triggered the Battle of Saipan

[As per an article published on ]

Possession of the Island of Saipan was a very critical objective for the US Forces owing to its location in the Mariana Islands which was equidistant between the Japan mainland and Philippines.

  • The US were aiming to acquire Saipan to make it a crucial air base, from where it could launch its long range B-29 bombers directly at Japan.
  • To cut off Japan Forces from the South of Saipan and the Japanese mainland itself.
  • Possession of the island was targeted to reduce resupply routes between the Japanese home islands and the Japanese garrisons in the Central Pacific, providing a niche for the US forces to acquire the other islands.
  • The US also envisioned that Saipan would serve as a springboard to acquire the Philippines in near future as per a post by W. Eugene Smith on

Let us dive into the Battle Details

  • In the early hours of 15 June, 1944, the US Forces stormed the beaches of the Saipan Island in amphibious landing vehicles. By the end of the day, there were more than 2000 US casualties.
  • The next morning, on 16 June, the Japanese launched a strong counter attack against the 4th Marine division. They cleverly put the civilians including the women and the children in the front of the attacking forces to create an impression that they were about to surrender.
  • After the tactic applied by the Japanese Forces, the US force stopped distinguishing between the combatants and the non-combatants, thus several civilians died at the hands of the US Marines.
  • The following days witnessed a tough clash between the US and the Japanese Forces.
  • June 30 was the beginning of the end of the Saipan Battle. The US forces kept moving facing tough resistance from the Japanese Forces.
