The 522nd Field Artillery Battalion had a reputation as one of the most accomplished artillery units in the European Theater of Operations, known for its speed and efficiency.1 The 522nd supported the 100th Infantry Battalion/442nd Regimental Combat Team infantry by providing artillery fire from its M101, 105mm (4.2 inch) light field Howitzers.
About 650 men served in the 522nd, which consisted of the Headquarters Company, three firing batteries (A, B, and C), Service Company, and a medical detachment.2 HQ Battery was in charge of the administration of the battalion, fire control, communication, and the medical team. The Service Battery maintained the motor pool, the mess hall, and supplies and equipment, including ammunition. The gun batteries each had four Howitzers pulled by a 6×6 truck.3 All worked together as a team.
The 522nd was activated on February 1, 1943, at Camp Shelby, Mississippi. At that time the unit consisted of nine white officers and 96 enlisted men of Japanese descent.
From February through April 18, they engaged in an intense training course. Then the 522nd had basic training alongside the 442nd from May to November 1943.4 Orville C. Shirey, the 442nd unit historian, notes that “the redlegs [a nickname for artillerymen] spent long, weary hours with their 105mm howitzers going into action and out of action till they were blue in the face; learning to serve the piece; learning the fundamentals of fuze and trajectory, observation and range.”5 In late November, after a successful platoon and company training, the unit then headed to Louisiana to practice war maneuvers. It rejoined the 442nd on February 7, 1944.
Each forward observer team had an officer who made decisions on the targets, a radio operator or wireman who communicated information to headquarters, and an instrument man who calculated the target coordinates. The Headquarters Battery coordinated the artillery attack. The battalion’s survey team provided accurate gun-position information, and the fire detection team determined how the guns were to be fired. Each battery’s instrument section oriented the horizontal and vertical controls on the guns. There was also an air observation group working two Piper Cub airplanes, determining the positions of the enemy and their artillery from above.
The seven members of each gun crew worked in unison, each performing a specific job with careful accuracy. They positioned the gun with the proper horizontal and vertical settings, packaged the powder charge, cut the fuse setting, put together the shells and casing, loaded the shells into the gun, and fired the gun. Everything had to be done with speed and precision.
At first, if the target was large, usually only one gun was fired to register the target. Forward observers would then determine the accuracy of the shot. The fire detection center then made any needed mathematical adjustments. If the gun was on target, then headquarters called, “Fire for effect!” Then all four guns would fire until ordered to stop by headquarters.6
On the fourth day that the 442nd was battling to reach the Lost Battalion, the 522nd had another close call. The 36th (Texas) Division Commander, Major General John Dahlquist, ordered an immediate artillery strike on a particular set of coordinates. But these coordinates would have targeted the members of the “Lost Battalion.” The fire detection team and a forward observer from the 522nd quickly made adjustments to the coordinates, saving them from harm.
Many of the 522nd’s key men had backgrounds in science and engineering.9 The men needed strong mathematical skills to make the necessary calculations for firing the guns and hitting their targets. They used tools like protractors, straight edges and special slide rules to determine target distance, site angles, and time-fire fuse settings.10
In March 1945, the 522nd separated from the 442nd and was sent out as a roving battalion to help other units. The 442nd and the 34th Division as a whole had come to depend on the 522nd for its accurate shooting and its brave and skillful forward observers, and their separation was deeply felt on both sides.
The 522nd crossed the Rhine River with the 45th Division. Then, it provided the 44th Division with supporting fire in its attack on Mannheim.11 It joined the 63rd for the Neckar River crossing and capture of Heidelberg. On April 1, it joined the 4th Division in its drive on Aub. On April 26, it crossed the Danube River with the 12th Infantry.
The 522nd was an integral component of the 442nd Regimental Combat Team. Yet the unit itself also stood alone for its remarkable accomplishments. The 522nd successfully completed every one of its 52 assignments, supporting more than seven different army divisions and units.14 The men traveled 1,100 miles in pursuit of the retreating Germans, from the Saar and Rhine Rivers to the Austrian border.15

(Author House: 2007), p. 125. Many of the 522nd soldiers were shocked and traumatized by what they witnessed and did not record specific names, dates, places or other such details, but instead referred to the “Dachau camps” in general, casting some doubt as to exactly what they had encountered and where. The 522nd was in range of at least six subcamps on April 29 and 14 others on April 30. For a list of the subcamps that the 522nd was near on April 29-30, see the unit’s history, 522nd Field Artillery Battalion, 442nd Regimental Combat Team, Fire for Effect (Honolulu, HI: Fisher Printing Co., 1998), p. 75.
