Shortly before 1000, Taplett ordered Company G to seize Sowolmi-do. Bohn in turn assigned the mission to one infantry squad reinforced with machine guns and a section of tanks, all under the control of Second Lieutenant John D. Counselman, leader of George Company’s 3d Platoon. Although the islet was by no means an objective of formidable proportions, the attackers eyed their route of approach over the long strip with misgivings. Their skepticism was not unfounded, for they neared the entrance to the causeway only to be stopped cold by heavy rifle and machine-gun fire from the other end. A platoon of North Koreans, almost literally at the end of a rope, preferred to fight it out.
Taplett ordered the tank-infantry team to hold up while he radioed a mission to Marine air. A few minutes later, Corsairs of VMF-214 nosed down and scorched the objective with napalm.
Sweet’s tanks, preceded by an engineer mine-clearance team and followed by the column of infantrymen, rumbled onto the rock bed tracing the seaward edge of the causeway. As the task force filed across the exposed route, 81mm shells from 3/5’s mortar platoon rattled overhead and tore into the Communist emplacements. Enemy fire was reduced to a light patter, and the observers on Radio Hill breathed a sigh of relief when the attackers gained the far end of the causeway at 1048.
Covered by tank fire, the Marine infantry quickly fanned out and closed with the defenders. There was a sharp outburst of small-arms racket, interspersed with the clatter of machine guns; then a few scattered volleys and the main fight was over at 1115. Mopping up with grenades and a flame thrower continued for almost another hour, owing to the number of caves and the determination of a few Red soldiers.
Nineteen North Koreans surrendered and 17 were killed, including some hapless warriors who tried to swim to the mainland. Despite the size of the islet, eight Reds succeeded in hiding out from the attackers; and General Craig, after landing on Wolmi-do with the ADC group in the evening, observed the fugitives escape to the mainland.[127]

The Two Harbor Islands Secured
Three Marines were wounded on Sowolmi-do, bringing 3/5’s total casualties for the day to 17 WIA. In return, Taplett’s battalion could count 136 prisoners and 108 enemy dead. Since interrogation of captives established the original number of Red defenders at 400, it could be concluded that some 150 more Communist fatalities lay entombed in sealed emplacements and caves throughout the island.
The Wolmi-do garrison was part of a 2,000-man force committed to the defense of Inchon by NKPA headquarters in Seoul. Represented were elements of the 226th Marine Regiment, to which two companies of the 2d Battalion, 918th Coast Artillery Regiment were attached with their Soviet-manufactured 76mm guns. The spiritless resistance encountered by 3/5 was the natural reaction of green troops to the awesome power of modern combined arms; for the North Korean marines and their artillerymen were largely recent conscripts with sketchy training and no experience. It remained to be seen how the other 1,600 Red troops would respond to the later assaults on RED and BLUE Beaches.
Mopping-up operations on the island were completed by noon, and with the support ships standing silent in the narrows, an oppressive quiet settled on the objective area. Gradually the phenomenal tide rolled back from its morning high of more than 30 feet. By 1300 the waters had receded, leaving 3/5 perched on an island in a sea of mud. For the next several hours Taplett and his men were on their own, speculating whether an enemy force might suddenly rush out of Inchon’s dead streets in an attempt to cross the mud flats, or whether a Red tank column would abruptly streak from the city and make for the causeway.
