From US Army Official History:

The Huggins Road Block was located between Soputa and Sanananda near the junction of the Soputa Track and Sanananda Track and the second junction with the Cape Killerton Track to Cape Killerton. Also known as simply the "Road Block", "Huggins Block" or by the 163rd Infantry Regimental code name "Musket" or "Old Huggins".

On November 30, 1942 U. S. Army soldiers from the 32nd Infantry Division, 126th Infantry Regiment's I Company under the command of 1st Lt. Hershel G. Horton plus the Anti-Tank Company under the command of Captain John Shirley reached a position on the trail to Sanananda by 6:30pm and established a road block to prevent the Japanese from advancing and enveloped their forward positions.

On December 1, 1942 a relief column led by Captain Meredith M. Huggins, S-3 from the 3d Battalion, 126th Infantry Regiment attempted to reach the road block with supplies and rations but had to fight their way into the road block perimeter, arriving safely at 11:00am. Soon afterwards, the Japanese launched a heavy counter attack and occupied to within 50 yards from the northeastern perimeter. On December 2, 1942 at 12:40pm Captain John Shirley was killed . After his loss, Captain Huggins took command and the position was named "Huggins Road Block" in his honor. During the attack, 1st Lt. Hershel G. Horton who later was wounded in action outside the perimeter and died of his wounds days later.

During December, Japanese attacked the area from all sides and attempted to isolate it from resupply and overcome the road block.

After the fall of Buna on January 3, 1943 the 1st Battalion, 163d Infantry, and regimental headquarters took over complete responsibility for the roadblock area that was now a well developed defensive position with inner and outer perimeter in square or circular formation for rifle and automatic weapon pits connected with trenches. Each squad was spaced approximately 15 yards apart. At the center of the position was a field kitchen, headquarters, switchboard, aid station, water purification, ammunition dump and supporting 81mm mortars plus two 37mm guns firing canister shot. Supplies were delivered by natives working in shifts and evacuating the wounded.

On January 4, 1943 the 1st Battalion, 163d Infantry Regiment began clearing of the area between Huggins and Kano. The 2d Battalion, 163d Infantry Regiment captured position along the Cape Killerton Trail to the west of Huggins. The Australian Army 18th Brigade was tasked with clearing enemy opposition south of Huggins.

By January 16, 1943 the positions between Huggins and James was reduced as the last major Japanese resistance along the Sanananda Track.
