There were 52 men and 36 dogs in the K-9 company on Bougainville.


The Coconut Grove Battle

On D plus 10, 11 November, a new operation order was issued. “Continue the attack with the 3d Marine Division on the right (east) and the 37th Infantry Division on the left (west).” An Army-Marine artillery group was assembled under IMAC control to provide massed fire, and Marine air would be on call for close support.

The first objective in the renewed push was to seize control of the critical junction of the Numa-Numa Trail and the East-West trail. On 13 November a company of the 21st Marines led off the advance at 0800. At 1100 it was ambushed by a “sizeable” enemy force concealed in a coconut palm grove near the trail junction. The Japanese had won the race to the crossroads, and the situation for the lead Marine company soon became critical. The 2d Battalion commander, Lieutenant Colonel Eustace R. Smoak, sent up his executive officer, Major Glenn Fissell, with 12th Marines’ artillery observers. They reported the situation as all bad. Then Major Fissell was killed. Disdaining flank security, Smoak moved closer to the fight and fed in reinforcing companies. (By now a lateral road across the front of the perimeter had been built.)

The next day tanks were brought up and artillery registered around the battalion. Smoak also called in 18 torpedo bombers. The reorganized riflemen lunged forward again in a renewed attack. The tanks proved an ineffective disaster, causing chaos at one point by firing on fellow Marines on their flank and running over several of their own men. Nevertheless, the Japanese positions were overrun by the end of the day, with the enemy survivors driven off into a swamp. The Marines now commanded the junction of the two vital trails. As a result, the entire beachhead was able to spring forward 1,000 to 1,500 yards, reaching Inland Defense Line D, 5,000 yards from the beach.

“Marine Drive” constructed by the 53d Naval Construction Battalion enabled casualties to be sent to medical facilities in the rear and supplies to be brought forward easily.

One important result of this advance was that the two main airstrips could now be built. The airfields would be the work of the Seabees. The 25th, 53d, and 71st Naval Construction Battalions (“Seabees”) had landed on D-Day with the assault waves of the 3d Marine Division—to get ready at once to build roads, airfields, and camp areas. (They had a fighter strip operating at Torokina by December). Always close to Marines, the Seabees earned their merit in the eyes of the Leathernecks. Often Marines had to clear the way with fire so a Seabee could do his work. Many would recall the bold Seabee bulldozer driver covering a sputtering machine gun nest with his blade. Marines on the Piva Trail later saw another determined bulldozer operator filling in holes in the tarmac of his burgeoning bomber strip as fast as Japanese artillery could tear it up. Any Marine who returned from the dismal swamps toward the beach would retain the wonderment of the “Marine Drive.” It was a two-lane asphalt highway, complete with wide shoulders and drainage ditches. It lay across jungle so dense that the tired men had had to hack their way through it only a week or so before.
