What battle took 4 months for the marines to defeat the Japanese?

Guadalcanal was probably closer to 6 months. However, the television history series has, probably for financial reasons, chosen to ignore the REAL battle for the islands. And that was the naval battles fought around Guadalcanal. Apparently it's too expensive for Hollywood to re-enact Naval Battle Scenes, so they do the cheaper parts of the battle by hiring actors to portray US Marines fighting the "Battle of Guadalcanal." The Japanese & US Navies fought the most brutal and savage naval battles in military history around the islands of Guadalcanal in 1942. So many warships were lost in one area that it is still called "Iron Bottom Sound" today. The only US Navy ADMIRALS ever killed in a Naval SURFACE Action during WWII were killed there; Admirals Scott and Callahgan. Whichever side won the naval battle, would win the island. The Marines and Japanese fighting men would have been starved out if their respective warships lost control of the seas.
