“The Japs do not like our coordinated artillery fire nor do they like our attacks with the bayonet. When under fire from small arms they stay down in their holes and are easily approached. When attacking small groups of foxholes, our troops were able to keep the Japs down by fire from rifles and the Browning Automatic Rifle while some of our men approached and dropped hand grenades into their holes. This was our favorite mop-up method.
“When about to be run out of a position, the Japs seemed to feel it necessary to counterattack. These attacks were not well coordinated and were welcomed by our troops, who were able then to shoot down the enemy in great numbers. These Jap counterattacks were of a suicidal character and were pressed home regardless of losses until practically all of the counterattacking troops were exterminated.
“The enemy may believe that, in such terrain, he can hold up the advance of an entire battalion with three men and a light machine gun. In fact, however, he is critically vulnerable to intelligent action by officers and men who understand the necessity for immediate maneuver against small parties of the enemy seeking to hold them up. The fact was that small maneuvering patrols easily disposed of machine-gun positions on reverse slopes behind mountain spurs, whereas any tendency to lie down and call for artillery support would have resulted only in tremendous wastage of artillery fire in attempting to seek out targets which, in fact, were inaccessible to artillery fire.
“The Attu action likewise indicated that standard Japanese infiltration tactics can be offset by a system of ‘anti-termite’ patrols organized behind our lines, protecting our artillery, command posts, and supply lines. Wherever troops know that these friendly patrols are behind them, fire in their rear will mean to them simply that our patrols are exterminating the infiltrating Japs. This feeling was well expressed by General Nathan Bedford Forrest [Confederate cavalry commander, Civil War], when one of his staff officers approached him in great excitement and said, ‘General, the enemy is in our rear.’ Forrest calmly replied: ‘If they’re in our’n, we must be in their’n.’”
THE SOUTH PACIFIC
SECURITY IN THE JUNGLE
In Bivouac Report of Commanding General, 43d Division, New Georgia Campaign: “Security in bivouac was a big problem in this New Georgia operation. The Japs conducted harassing raids against our bivouac areas with some success for a period of about a week. Our initial plan had been adopted on the advice of other units experienced in jungle warfare. It called for complete immobility at night, with grenades and bayonets as the only defense weapons. Gun crews were directed to fire only in the event of a major attack. However, we found that small parties of Japs were able to filter into the battle areas and cause some casualties without being seriously opposed.
“This situation was effectively corrected by using a close perimeter defense. Men occupying these perimeter lines were ordered to fire at known targets. Machine guns were so laid that final protective lines covered the perimeter. The nature of the terrain and the type of night tactics employed by the Japanese made the establishment of outposts for security purposes inadvisable as visibility was limited to a few feet from any given outpost. Two men occupied each foxhole, one remaining awake and alert to all activity in his vicinity. Within the perimeter, machetes were used from the foxholes against any enemy raiders who were able to penetrate. This system effectively discouraged night raids.
On the March “March security adhered to established doctrine except that distances between the elements of the column were greatly reduced. Extremely limited visibility and the difficulty of moving through the jungle off the trails nearly always prevented close-in security detachments.”
