Major General Harry Clay Hale (July 10, 1861 – March 21, 1946) was a United States Army officer in the late 19th and early 20th centuries.

[1][3] Among his classmates included several future general officers, such as George Windle Read, Chase Wilmot Kennedy, Omar Bundy, George H. Cameron, Samson L. Faison, Lawrence Tyson, Charles Gould Morton, Tyree R. Rivers, George Windle Read, John Wilkinson Heard, Ira Allen Haynes, William Campbell Langfitt, John Wilson Ruckman, Robert D. Walsh, Isaac Littell and Clarence Ransom Edwards.

Also in 1915, Hale was sent to China to command the 15th Infantry Regiment, though he returned to the United States shortly afterward in order to organize the 84th Division at Camp Zachary Taylorl after the American entry into World War I.

[1][3] Walter Krueger, who would later rise to prominence during World War II, served for a while with the 84th Division as its chief of staff.

His brilliant professional attainments, his steadfast devotion to duty, and his loyalty to superiors were reflected in the high standards maintained throughout the divisions under his command, and he thus rendered important services to the American Expeditionary Forces and contributed conspicuously to the success of the operations.

[5][3] Hale lived in Palo Alto, California, or Rockville, Maryland,[3] during his retirement, and he died on March 21, 1946, at the age of 84.
