By the fourth day, there were as many casualties from heat prostration as from wounds. Peleliu is incomparably worse than Guam in its bloodiness, terror, climate and the incomprehensible tenacity of the Japs. For sheer brutality and fatigue, I think it surpasses anything yet seen in the Pacific.”
The stress of combat, combined with the unrelenting heat, made for a miserable combination. There was no way to escape the heat. The sun beat down relentlessly, turning the island “into a scorching furnace,” according to one unit after action report. Everyone was sunburned. Jagged coral rocks poked painfully into tender, sun-baked skin. Men sweated profusely. Their fatigues were salt-stained, dripping wet from their smelly perspiration. Salt tablets helped a little bit, but supplies were low. Some Marines collapsed from heat exhaustion. One officer in the 1st Battalion, 7th Marines, saw many such men in his outfit “unable to fight, unable to continue. Some were carried out with dry heaves. Others had tongues so swollen as to make it impossible for them to talk or to swallow. Others were unable to close eyelids over their dried, swollen eyeballs. We lost their much needed strength in a critical phase of the operation.”
Dehydrated, frightened, and exhausted, a few broke mentally under the strain of the heat. Private Russell Davis saw a big redheaded Marine, with dried lips and cherry red sunburned skin, completely lose his composure. “I can’t go the heat! I can take the war but not the heat!” he screamed. Davis watched as “he shook his fist up at the blazing sun. Two of his mates pounced on him and rode him down to the earth, but he was big and strong and he thrashed away from them.” Davis never knew the broken man’s ultimate fate. 18
To make matters infinitely worse, water was scarce. Each Marine came ashore with two canteens of water, a woefully inadequate ration for Peleliu’s killer heat. Most of the men drank their canteens dry within the first few hours of the invasion. “We had practiced water discipline at great length . . . but the body demands water,” Private Richard Johnston, a machine gunner in the 5th Marines, explained. “No matter how strong your will or how controlled your mind, you either drink what water you have or die in not too long a time.” Medical corpsmen were covered with the blood of wounded men, but now had no water to wash that blood off their hands. With no other choice, they treated their patients with filthy, bloodstained hands. After the chaos of the beach assault abated, and the battle settled into a steady push inland to gain ground, shore parties hauled water ashore, mostly in fifty-five-gallon drums and five-gallon cans. By the second or third day, this water reached the frontline fighters. When a five-gallon can reached Private Sledge’s K Company, 5th Marines, he anxiously held out his canteen cup for a drink. “Our hands shook, we were so eager to quench our thirst. The water looked brown in my aluminum canteen cup. No matter, I took a big gulp—and almost spit it out despite my terrible thirst. It was awful. Full of rust and oil, it stunk. A blue film of oil floated lazily on the surface of the smelly brown liquid. Cramps gripped the pit of my stomach.”
The drums and cans had originally been used to carry fuel. Before the invasion, work parties had not properly cleaned the containers. Thus, when they were filled with warm water, the fuel residue mixed with the water, and the metal of the containers, producing a noxious, unhealthy, rusted, repulsive brown liquid. “Smelling and tasting of gasoline, it was undrinkable,” Robert Leckie, a machine gunner in the 1st Marines, wrote. Nonetheless, many Marines, like Sledge, were so desperately thirsty that they drank the tainted water. Some vomited. Others were incapacitated with sharp cramps and had to be evacuated.
Word of the tainted water spread quickly. Soon the Marines began looking for other ways to slake
