Over the next few months, the tempo of operations increased, forcing the Sixth Army to plan and execute multiple operations simultaneously.[51] Operations Reckless and Persecution in April 1944 together comprised the largest operation yet in SWPA, with the 24th and 41st Infantry Divisions of Lieutenant General Robert L. Eichelberger's I Corps landing at Tanahmerah and Humboldt bays near Hollandia, while the 163rd Regimental Combat Team landed at Aitape.[52] Eichelberger was Krueger's most senior subordinate, but when he did not meet Krueger's expectation, Krueger let him know in no uncertain terms. "In my more than 40 years as an officer", Krueger told one of his staff, "I have never raised my voice to an enlisted man, but a corps commander should know better."[53]
