On 7 August 1942 the first stage of the offensive began with landings by a Marine division on Guadalcanal and nearby islands. The Japanese reacted vigorously. They inflicted a serious defeat on Ghormley's naval forces in the Battle of Savo Island (8 August 1942), landed large numbers of reinforcements on Guadalcanal, and ultimately lost strong ground, air and naval forces in a desperate effort to hold Guadalcanal. Six major naval engagements were fought off the island. Air battles raged almost daily until the end of October 1942. On shore the issue was in doubt for almost three months. Before the island was finally secured in February 1943, the United States had committed two Marine divisions, two Army divisions, and an additional Army regiment to the fight. Late in February 1943 an Army division was unopposed in taking the Russell Islands, 35 miles northwest of Guadalcanal. The Allies thus firmly established themselves in the Solomons.
