For the first 20 minutes, Johnston was helpless as the enemy cruisers and battleships had her in range. But the destroyer's 5-inch guns could not yet reach them. She charged onward to close the enemy: first a line of seven destroyers; next, one light and three heavy cruisers, then the four battleships. To the east appeared three other cruisers and several destroyers.
As soon as range closed, Johnston opened her 5-inch battery on the nearest cruiser, scoring damaging hits. About this time an 8-inch shell landed right off her bow, its red dye splashing the face of Johnston's gunnery officer, Lt. Robert C. Hagen. He mopped the dye from his eyes while remarking: "Looks like somebody's mad at us!" In 5 furious minutes Johnston pumped 200 rounds at the enemy, then Comdr. Evans ordered, "Fire torpedoes !" The destroyer got off 10 torpedoes then whipped around to retire behind a heavy smoke screen. When she came out of the smoke a minute later, Japanese cruiser Kumano could be seen burning furiously from torpedo hits. Kumano later sank. But Johnston took three 14-inch shell hits from a battleship followed closely by three 6-inch shells from a light cruiser: "It was like a puppy being smacked by a truck. The hits resulted in the loss of all power to the steering engine, all power to the three 5-inch guns in the after part of the ship, and rendered our gyro compass useless." Through "sheer providence" a rainstorm came up; and Johnston "ducked into it" for a few minutes of rapid repairs and salvage work.
At 7:50 a.m., Admiral Sprague ordered destroyers to make a torpedo attack. But Johnston had already expended torpedoes. With one engine, she couldn't keep up with the others: "But that wasn't Comdr. Evans' way of fighting: 'We'll go in with the destroyers and provide fire support,' he boomed." Johnston went in, dodging salvos and blasting back. As she charged out of blinding smoke, pointed straight at the bridge of gallant Heerman (DD-532), "All engines back full!" bellowed Comdr. Evans. That meant one engine for Johnston who could hardly do more than slow down. But Heerman's two engines backed her barely out of the collision course, Johnston missed her by less than 10 feet. Now there was so much smoke that Evans ordered no firing unless the gunnery officer could see the ship. "At 8:20, there suddenly appeared out of the smoke a 30,000-ton Kongo-class battleship, only 7,000 yards off our port beam. I took one look at the unmistakable pagoda mast, muttered, 'I sure as hell can see that!" and opened fire. In 40 seconds we got off 30 rounds, at least 15 of which hit the pagoda superstructure.... The BB belched a few 14-inchers at us, but, thank God, registered only clean misses."
Johnston soon observed Gambier Bay (CVE-73) under fire from a cruiser: "Comdr. Evans then gave me the most courageous order I've ever heard: 'Commence firing on that cruiser, draw her fire on us and away from Gambier Bay'." Johnston scored four hits in a deliberate slugging match with a heavy cruiser, then broke off the futile battle as the Japanese destroyer squadron was seen closing rapidly on the American escort carriers. Johnston outfought the entire Japanese destroyer squadron, concentrating on the lead ship until the enemy quit cold, then concentrated on the second destroyer until the remaining enemy units broke off to get out of effective gun range before launching torpedoes, all of which went wild.
Johnston took a hit which knocked out one forward gun, damaged another, and her bridge was rendered untenable by fires and explosions resulting from a hit in her 40mm. ready ammunition locker. Evans shifted his command to Johnston's fantail, yelling orders through an open hatch to men turning her rudder by hand. At one of her batteries a Texan kept calling "More shells! More shells!" Still the destroyer battled desperately to keep the Japanese destroyers and cruisers from reaching the five surviving American carriers: "We were now in a position where all the gallantry and guts in the world couldn't save us, but we figured that help for the carrier must be on the way, and every minute's delay might count.... By 9:30 we were going dead in the water; even the Japanese couldn't miss us. They made a sort of running semicircle around our ship, shooting at us like a bunch of Indians attacking a prairie schooner. Our lone engine and fire room was knocked out; we lost all power, and even the indomitable skipper knew we were finished. At 9:45 he gave the saddest order a captain can give: 'Abandon Ship.'... At 10:10 Johnston rolled over and began to sink. A Japanese destroyer came up to 1,000 yards and pumped a final shot into her to make sure she went down. A survivor saw the Japanese captain salute her as she went down. That was the end of Johnston."
From Johnston's complement of 327, only 141 were saved. Of 186 lost, about 50 were killed by enemy action, 45 died on rafts from battle injuries; and 92, including Comdr. Evans, were alive in the water after Johnston sank, but were never heard from again.
