When the US government approved the formation of an all Nisei combat unit, it was with the understanding that white officers would lead the team as a whole. Of the units that comprised the Nisei 442nd Regimental Combat Team, the 232nd Combat Engineer Company was unique because it was run by Japanese American officers, not white ones. Captain Pershing Nakada, a 25-year old Nisei, and seven Nisei officers led about 200 enlisted men.1
The men of the 232nd tended to be older than most men in the infantry and the artillery. The majority of them had a high school diploma, and many had backgrounds in engineering and the sciences. Nakada himself had a mechanical engineering degree from the University of Nebraska.2
The combat engineers’ role was to keep the lines of communication and transportation open for the infantry. While construction engineers supported occupied areas, the combat engineers were at the front. They ensured that the wounded could be evacuated. They also ensured that needed supplies could make their way to the men. They cleared the way so that the unit could quickly and safely move forward, and supplies and the wounded could be transported. They swept areas for enemy mines along the unit’s path and laid mines of their own for their defense. They built abatis, field fortifications made of fallen trees and often booby-trapped. They felled trees to build roads and constructed bridges.
The Germans didn’t make the work easy. On October 15, 1944, near Bruyères, France, the infantry encountered a quarter-mile long roadblock of logs and fallen trees. It was the only supply and evacuation route available, and it was heavily booby-trapped.3 As the engineers worked to clear the way, the Germans fired at them from four machine gun nests.4 Riflemen from the 100th Infantry Battalion assisted them in silencing all four nests, and the engineers returned to their work.5 For eight and a half hours, under intermittent heavy mortar and artillery fire, the engineers defused mines and hand-sawed the downed trees.6
From October 27-30, two platoons of engineers accompanied front-line infantrymen during the rescue of the Lost Battalion. For four days the engineers endured enemy fire and the cold wet weather, but they managed to clear more than 30 mines in the path of the advancing infantry. They worked day and night, stopping only to eat or sleep for brief moments.7
Near Biffontaine, another engineer unit refused to clear a minefield because of heavy enemy fire. The 232nd stepped in and cleared the field, allowing the grateful infantrymen to advance.8
Throughout the Vosges campaign the rugged terrain and wet weather made the 232nd’s job of keeping the supply lines open even tougher. The few narrow logging roads that crossed the steep wooded hills were quickly turned to soggy bogs. The three platoons worked constantly in 12-hour shifts. They laid more than a mile of plank-board, dumped truckloads of gravel and built culverts across badly shelled roads.
From November 6-8, the engineers stopped their day-and-night work to become infantrymen and relieve the exhausted and decimated 100th Battalion A Company.9 The engineers also served as infantry riflemen in the Rome-Arno and the Po Valley Campaigns.10
During the drive on the Gothic Line, squads of engineers were frequently assigned to clear gaps through minefields and do other engineer work during infantry assaults.11 Meanwhile the rest of the 232nd worked to keep the supply lines open for the swift-moving infantry.12
While the infantrymen wielded rifles, machine guns, and bazookas, the engineers used bulldozers, saws, and minesweepers as their “weapons.” While the infantrymen cleared machine gun nests, the engineers cleared roads. Although combat was not their primary function, the engineers still faced enemy sniper, mortar and artillery fire and the constant danger of booby traps and mines. Nearly 30 percent of the engineers were wounded and seven died because of their hazardous work keeping the supply lines open.19
The 232nd provided one additional thing that earned the gratitude of the infantrymen: hot showers. For soldiers facing cold, wet weather and trudging through thick mud, hot showers did wonders for their morale, even if the showers themselves were infrequent and only three minutes in length.20
The engineers devised an ingenious portable hot shower unit, built using bits and parts retrieved along the way: an American jeep engine, a German electric dynamo, a fuel pump motor from an Italian self-propelled gun, a condenser from a beer factory, and shower heads salvaged from a demolished resort hotel. The shower unit was capable of producing 50 gallons of hot water a minute. Thanks to the engineers, the 442nd was likely the only regiment to enjoy hot showers in combat.21
