Guadalcanal 1942: Operation Watchtower, Alligator Creek and Henderson Field

How did Operation Watchtower seize Guadalcanal and secure Henderson Field in 1942? This episode follows the landings, night sea battles, and brutal fights at Alligator Creek. Japan's rapid expansion after Pearl Harbor put Allied supply lines to Australia at risk when an airfield rose on Guadalcanal. In this Battlefield episode, American planners launch Operation Watchtower under Vice Admiral Robert L. Gormley, tasking Major General Alexander A. Van der Grift's 1st Marine Division despite rushed rehearsals in Fiji, influenza, and dock strikes in Wellington. Naval cover comes from Rear Admirals Frank J. Fletcher and Richmond J. Turner with carriers Saratoga, Wasp, and Enterprise. On 7 August 1942, Marines land at Red Beach and seize the nearly completed airstrip, soon named Henderson Field, while Edson's Marine Raiders battle through Tulagi, Gavutu, and Tamonbogo. That night, Vice Admiral Gunichi Mikawa drives a cruiser strike through the Slot, launching the Battle of Sarvo Island and sinking four Allied cruisers. Hours later, Fletcher withdraws the carriers; Turner pulls the transports, leaving half the supplies aboard and the Marines isolated. Digging in around Henderson, the Marines meet Colonel Ichiki's 2nd Battalion at Alligator Creek in the Battle of the Temaru. Repeated Japanese bayonet charges crash into American artillery, machine guns, light armor, and SBD Dauntless strikes. By afternoon, Ichiki's force is shattered, with roughly 800 dead. Through late August and September, the Tokyo Express, conceived by Rear Admiral Tanaka, delivers reinforcements. After a clash at Tassimbako, Kawaguchi's brigade attacks the ridge south of the airfield, remembered as Bloody guch. Twelve night assaults are thrown back by raiders and paratroops; Henderson Field holds. In October, Lieutenant General Hayukutaki massed 20,000 men. Major General Sumiyoshi's western tanks are crushed by American artillery and 37mm canister; General Mariyama's southern force arrives late and without heavy weapons. The Marines prevail again, even as the carrier Hornet is lost at Santa Cruz. By early December, Van der Grift's exhausted troops are relieved; by February 8, remaining Japanese forces evacuate. The supply lifeline to Australia is secure, and the long road across the Pacific begins. Featuring the weapons and machines that shaped the campaign, from F4F Wildcats, SBD Dauntlesses, and P400s to the M3 tank, M1 Garand, 75mm pack howitzers, and the Japanese Type 99 rifle, Type 92 guns, Zero fighters, and Betty bombers, this is a clear, ground-level view of Guadalcanal's turning-point battles. #Guadalcanal #OperationWatchtower #HendersonField #TokyoExpress #USMarines #PacificWar #SarvoIsland #WW2
