Karl D. Klemm

Karl D. Klemm was a U.S. Army artillery officer whose command brought him into conflict with Harry S. Truman during the First World War. Efficient and strict, Klemm embodied an exacting style of military authority; on a difficult march in France, Truman’s willingness to protect exhausted soldiers brought that style into sharp relief. Klemm remained a troubling figure in Truman’s recollections, and his later death by suicide gave the account of their wartime conflict a somber coda.

Identity and Command

Klemm was from Kansas City and graduated from West Point in the Class of 1905. He was elected to his position, as Truman had been, and was regarded as capable but humorless and uncompromising. His manner was described as resembling that of a Prussian officer: a comparison that conveys the severity associated with his command, rather than a claim about his national identity. Truman later acknowledged that the men who had elected Klemm came to regret the choice.

Klemm’s relationship with Truman was not simply that of a senior officer and a subordinate. At Truman’s urging, Klemm and Lieutenant Colonel Robert M. Danford joined the Masons, an association Truman believed helped expand his influence among officers. The two men, both graduates of the West Point class Truman would have joined had he been admitted, offered contrasting examples of leadership. Danford was an exacting disciplinarian, but also treated those under him with kindness and understanding. Truman remembered learning from Danford’s practical instruction in artillery and in handling men. Klemm, by contrast, became a source of considerable difficulty for Truman and others.

Battery Command and Conflict on the March

In July 1918, at Camp Coëtquidan in France, Klemm summoned Truman and directed him to take command of Battery D of the 2nd Battalion, 129th Field Artillery. The appointment fulfilled Truman’s highest ambition, but also placed him in charge of four guns and 194 men. Klemm’s decision therefore made him a direct part of the circumstances that launched Truman into battery command, even as their subsequent dealings tested the new commander’s judgment and authority.

During a weeklong march, darkness, rain, and mud made movement difficult. Horses were failing, while artillerymen walking behind the guns were ordered not to hold onto them or their caissons, so as not to add to the animals’ burden. In these conditions, Klemm rode up and down the line shouting orders and directed an advance at double-time up a long hill. His behavior alarmed the men. Some later wondered whether he had temporarily lost control or was drunk, but the account presents these as retrospective speculation, not an established explanation.

Truman took his men off the road to rest. When Klemm challenged him, Truman replied that he was carrying out orders. The men’s regard for him grew after the exchange. The confrontation turned on a difference in how each officer exercised command: Klemm demanded continued movement, while Truman judged that his exhausted soldiers needed a pause. The episode established Truman’s authority not by defying the chain of command in public, but by presenting his decision as consistent with his responsibilities.

A further dispute arose when Truman allowed Sergeant Jim Doherty, who had a twisted ankle, to ride his horse, contrary to orders. Klemm saw Doherty and angrily ordered him to dismount. Truman insisted that Doherty would remain mounted while Truman was in command of the battery. Klemm rode away furious. Truman recorded the insult in his diary, making clear that he took the confrontation as a personal as well as a professional affront. The episode also sharpened the contrast between formal obedience and the discretion Truman believed a commander owed to the men under him.

Reputation and Aftermath

The conflict became part of the way Truman and the men remembered Klemm. In recollections long after the march, some soldiers speculated about the cause of his conduct, while Truman’s diary preserved his anger at Klemm’s treatment of him. These different traces do not settle what was behind Klemm’s actions; they show instead how strongly the march and its command disputes remained in memory. Klemm’s strictness was not an isolated impression: he was already regarded as humorless and demanding, and his conduct on the road reinforced that reputation.

Klemm’s subsequent fate added a stark ending to this recollection. In 1925, in his Kansas City business office, he died by suicide. The account does not establish a connection between that death and his wartime service or his conflict with Truman. Rather than resolving the earlier disputes, it leaves them as a remembered encounter with an officer whose authority Truman could neither ignore nor fully accept.

Narrative Role

Klemm’s significance lies chiefly in the way his command illuminates Truman’s early development as an officer. He is presented through concrete tests of authority: the appointment of Truman to Battery D, the order to hurry the men up the hill, and the dispute over Doherty’s ride. Against those demands, Truman’s decisions take shape as a style of leadership that combines discipline with attention to individual circumstances. The contrast with Danford makes the distinction clearer: both officers could be exacting, but Danford’s example joined discipline to patient instruction, while Klemm’s became associated with strain and conflict.

The narrative does not offer a full account of Klemm’s life or explain his motives. Its portrait is narrower and more consequential: a strict commander remembered through the pressure he placed on Truman and the soldiers, and through the insubordination Truman resisted in order to protect his men. Klemm thus serves as both a real military superior and a measure of the kind of command Truman was beginning to define for himself.
