Maruyama's first attacks on the perimeter
With the redeployment of Hanneken's battalion, the 700 troops of 1st Battalion, 7th Marines under Lieutenant Colonel
Chesty Puller were left alone to hold the entire 2,500 yd (2,300 m) line on the southern face of the Lunga perimeter east of the Lunga River. Late on 24 October, Marine patrols detected Maruyama's approaching forces, but it was now too late in the day for the Marines to rearrange their dispositions.

At 14:00 on 24 October, Maruyama's left and right wing units began to deploy for their attacks. Maruyama's troops had very little artillery or mortar support for their upcoming assault, having abandoned most of their heavy cannons along the Maruyama Road. Between 16:00 and 21:00, heavy rain fell, delaying the Japanese approach and causing "chaos" in the Japanese formations, already exhausted from the long march through the jungle. Shoji's right wing force accidentally turned parallel to the Marine lines, and all but one battalion failed to make contact with the Marine defenses. Shoji's 1st Battalion, 230th Infantry Regiment "stumbled" into Puller's lines about 22:00 and were driven off by Puller's men. For unknown reasons, Maruyama's staff then reported to Hyakutake that Shoji's men had overrun Henderson Field. At 00:50 on 25 October, Hyakutake signaled Rabaul that, "A little before 23:00 the Right Wing captured the airfield."
At about this time, Nasu's left wing battalions finally began to reach the Marine defenses. At 00:30 on 25 October, the 11th Company of Nasu's 3rd Battalion under Captain Jiro Katsumata found and attacked Company A of Puller's battalion. Katsumata's attack was impeded by heavy barbed wire in front of the Marine line and then hit heavily by American machine gun, mortar, and artillery fire. By 01:00, the Marine fire had killed most of Katsumata's company.
Further west, the 9th Company of Nasu's 3rd Battalion charged straight into Puller's Company C at 01:15. Within five minutes, a Marine machine gun section led by
Sergeant John Basilone killed almost every member of the 9th Company. By 01:25, heavy fire from the Marine divisional artillery was falling into Nasu's troop assembly and approach routes, causing heavy casualties.
Recognizing that a major Japanese attack was underway, Puller requested reinforcement. At 03:45, the 3rd Battalion, 164th Infantry, commanded by Lieutenant Colonel Robert Hall and being held in reserve, was fed piecemeal into Puller's line. In spite of the darkness and intermittent heavy rain, the Army National Guard troops were placed in Puller's defenses before daybreak.
Just before dawn, Colonel Masajiro Furimiya, the commander of the 29th Infantry, with two companies from his 3rd Battalion plus his headquarters staff, was able to penetrate the Marine artillery fire and reach Puller's lines about 03:30. Most of Furimiya's troops were killed during their assault, but about 100 broke through the American defenses and carved a
salient 150 yd (140 m) in width and 100 yd (91 m) deep in the center of Puller's line. After sunrise, Furimiya's 2nd Battalion joined in the assault on Puller, but were thrown back. At 07:30, Nasu decided to withdraw most of the remainder of his troops back into the jungle and prepare for another attack that night
During the day of 25 October, Puller's men attacked and eradicated the salient in their lines and hunted small groups of Japanese infiltrators, killing 104 Japanese soldiers. More than 300 of Maruyama's men in total were killed in their first attacks on the Lunga perimeter. At 04:30, Hyakutake rescinded the message announcing the capture of the airfield, but at 07:00 declared that the results of Maruyama's attack were unknown.
Naval and air attacks

The Japanese 8th Fleet had task units ready to support the Army's attacks on Guadalcanal. Upon receipt of Hyakutake's message declaring success at 00:50 on 24 October, the task units went into action. The light cruiser Sendai and three destroyers patrolled west of Guadalcanal to interdict any Allied ships that tried to approach the island. A First Assault Unit with three destroyers and a Second Assault Unit with the light cruiser Yura and five destroyers approached Guadalcanal to attack any Allied ships off the island's north or east coast and to provide gunfire support for Hyakutake's forces.
At 10:14, the First Assault Unit arrived off Lunga Point and chased away two old U.S. destroyers converted to
minesweepers— Zane and Trever —which were delivering aviation fuel to Henderson Field. The Japanese destroyers then sighted and sank the U.S. tugboat
Seminole and patrol boat YP-284 before beginning their bombardment of the U.S. positions around Lunga Point. At 10:53, a Marine shore gun hit and damaged the destroyer Akatsuki, and all three Japanese destroyers withdrew while being strafed by four CAF Wildcat fighters. As the Second Assault Unit approached Guadalcanal through
Indispensable Strait , it was attacked by five CAF SBD-3 Dauntless dive bombers. Bomb hits caused heavy damage to Yura, and the unit reversed course to try to escape. More CAF air attacks on Yura throughout the day caused further damage, and the cruiser was abandoned and scuttled at 21:00 that night.
Meanwhile, 82 Japanese bombers and fighters from the 11th Air Fleet and from the aircraft carriers Junyō and Hiyō attacked Henderson Field in six waves throughout the day and were engaged by CAF fighters and Marine anti-aircraft guns. By the end of the day, the Japanese had lost 11 fighters, two bombers, and one reconnaissance aircraft along with most of the aircrews in the downed aircraft. Two CAF fighters were destroyed in the day's fighting but both pilots survived. The Japanese air attacks caused only light damage to Henderson Field and the American defenses. The Americans later referred to this day as "Dugout Sunday" because the continuous Japanese air, naval, and artillery attacks kept many of the Lunga defenders in their foxholes and shelters throughout the day.
