The Japanese, reluctant to risk their remaining carriers in a major engagement in the Solomons until they had a good land airfield, decided to seize Henderson Field on Guadalcanal. The land offensive commenced on 23 October1942 but the Marines managed to repulse each assault. Vice Admiral Halsey, the Commander of the South Pacific Area, sent the Hornet and Enterprise to attack the Japanese fleet cruising northeast of the Solomons.
On 26 October both carrier forces launched their aircraft against each other in an exchange of strikes which damaged Hornet and Shokaku. In two subsequent attacks from Shokaku and ZuikakuEnterprise was hit and damaged while Hornet was set ablaze, abandoned, and later sunk by the Japanese destroyersAkigumo and Makigumo. The Americans retreated eastwards to get air cover from the land bases in the New Hebrides but the Japanese, still cautious because of their defeat at Midway, failed to pursue the American fleet and lost the opportunity to sink or damage Enterprise.

While the army of the Confederate Protector was made up of veterans of internal battles and was supported by the population, besides counting on adequate supplies provided by the vicinity, the Chilean Army met with the antipathy of the inhabitants and was on the run, with part of the troops ill and little prepared.
The Battle of Yungay brought as a consequence the end of the Peru-Bolivian Confederacy, the cessation of SantaCruz' influence in Bolivia - in spite of up to six subsequent uprisings in his name in Bolivia - and the restoration of both nationsas separate, as was the intention of the Recovery Expedition.
These naval battles did not produce a victor, but the Japanese were unable to replace their losses.
The land battle hinged around the airfield which the Americans named Henderson Field, a muddy airstrip hanging onto the edge of the island, and considered "an unsinkable aircraft carrier".
