Archivist Attic – Acey Bone at Incheon

In September 1950 the personnel and equipment of Acey Bone (ACBONE), the familiar name of Amphibious Construction Battalion ONE, participated in the invasion of Inchon, Korea. This decisive victory turned the tide in favor of the United Nations and enabled the recapture of Seoul, South Korea, a few weeks later. Acey Bone was able to set up piers, a tent city, and even provide entertainment, quicker than you can get through your holiday celebrations!

On the morning of September 15th, the Marine Landing Force made its assault at Inchon. The Seabees were right on their heels and one and a half hours after the first waves hit the beach the Seabees had the pontoon cause way launched, assembled, and ready for beaching.

Natural obstacles proved the biggest test for building the harbor. Tidal flats and extreme tides led to maximum tidal currents against which the causeway could not be maneuvered. Working against time and tide, the pier was installed after two unsuccessful attempts. Placement of the pier had to be carefully planned in order to provide constant accessibility during both high and low tides.

Even with all the Seabee ingenuity, tidal conditions continued to limit operations. To combat this, small crafts were employed to maintain a constant flow of materials across the pier. The combination of pier work and small craft permitted 24-hour utilization of the vital links.

While pontoons were being placed in the harbor, the beach conditions were also being improved in order to make a workable base. A tent city was constructed while drivers improved roads improving the flow of materials. Seabees with railroad experience also brought Korean locomotives through enemy mortar and fire to supply the troops. They manned this equipment for the duration of their stay. Their fortitude and unusual skill provided unexpected service in support of the logistic operations.

All work and no play makes even the best military cranky. No problem with that though, the Seabees took care of that when they installed a theater. The theater proved so popular that once again, the traditional “Courtesy of the Seabees” sign was displayed on a beachhead.

Consolidation and improvement operations continued until October 1950, by which time the preliminary work was done and the Base Development phase commenced. In just three short weeks the Seabees had built a pontoon cause way, installed a tent city, worked on making a railway functional, and provided entertainment for the troops! All because Seabees Can Do!
