Kalsu humped those 97-pound explosive rounds along with his men, an officer exposing himself to fire when he could have stayed in the bunker. "A fearless guy, smart, brave and respected by his troops," recalls retired colonel Philip Michaud, who at the time was a captain commanding the ill-fated battery of 105s. "Rounds were coming in, and he was out there. I told him a few times, 'It's good to run around and show what leadership is about, but when rounds are blowing up in your area, you ought to hunker down behind a gun wheel. Or a bunker.' The guy thought he was invincible."
The grunts loved him for it, and they would have followed him anywhere. David Johnson always did. Kalsu and Johnson, by most superficial measures, could not have been more different. Kalsu was white and the only child of middle-class parents—city-bred, college-educated, married, a father, devoutly Catholic. Johnson was black and the seventh of 11 children raised on a poor farm outside of Humnoke, Ark. He was single and childless, a supplicant at the Church of God and Christ. What the two men shared was a gentleness and childlike humanity that reached far beyond race. So James Robert Kalsu, 25, and Spc. 4th Class David Earl Johnson, 24, became inseparable. "They just clicked," recalls former sergeant Alfred Martin. "You saw one, you saw the other."
That lull in incoming fire on July 21 nearly brought the two friends together again. Johnson was standing outside Kalsu's bunker on the pock-marked hill. Cpl. Mike Renner, a gunner, was standing by his 155 with a sergeant who was dressing him down because the jack on the gun had broken, leaving the crew unable to raise it to a different azimuth. At that moment Kalsu and Fotias rose out of the bunker. They stood at the door for a moment, Fotias with his back to it, and Kalsu started reading to him from a piece of paper in his hand. "[It was] a letter he had received from his wife," Fotias says. "I remember the joy on his face as he read the letter to me. He said, 'My wife's having our baby today' "
Some rounds you heard falling, some you didn't. Fotias did not hear this one. Jim Harris, the battalion surgeon, was across the firebase when he heard the splitting crack and turned his head toward it. The 82-mm mortar landed five feet from the bunker door. "I can still feel the heat of the blast coming past me and the concussion knocking me over," says Renner. "It flipped me backward, my helmet flew off, and the back of my head hit the ground."
Johnson fell sprawling on the ground. Fotias, at the mouth of the bunker, saw the sun go out. "I remember this tremendous noise," he says, "and darkness. And being blown off my feet and flying through the door of the bunker and landing at the bottom of the steps, six feet down, and this tremendous weight crushing me. I couldn't see. I couldn't hear. I had dirt in my eyes, and my eyes were tearing. I rubbed them, and then I could see again. I pushed off this weight that was on top of me, and I realized it was Bob."
Kalsu was really a boy trapped inside a large man's body—a player of pranks whose high-pitched cackle would fill a room. He laughed so heartily that he drooled, the spittle coursing from the corners of his mouth down around his dimpled chin and on down his chiseled neck. Once, on hearing the punch line of an off-color joke, he slammed a fist so hard on an adjoining barstool that the stool broke into pieces. He had the appetite of a Komodo dragon, but he loved kids even more than food. Some valve must have been missing in his psyche: His ego, unlike that of most jocks, was not inflatable. He always favored the underdog (he arranged the selection of one girl as high school homecoming queen because no one paid her much mind), and he turned down a high school sports award on grounds that he'd already received too many. "It'll mean more to somebody else," he told his mother, Leah.
Kalsu was born in Oklahoma City on April 13, 1945, and he came of age in the suburb of Del City at a time when coach Bud Wilkinson was leading Oklahoma through its gilded age. From 1953 into '57 the Sooners won 47 consecutive games, still a record for a Division I school, and finished three straight seasons ('54 to '56) undefeated. Twice during that run, in '55 and '56, they were national champions. Like every other 18-year-old gridiron star in the state, Kalsu aspired to play in Norman. Even as Wilkinson's program faltered in the early 1960s—the Sooners were 16-14-1 in the first three years of the decade—the coach's aura was so strong that there was only one place for a local kid to go. When Wilkinson recruited Kalsu out of Del City High in '63, Kalsu signed on.
He was not the first in his family to make the big time in Oklahoma college sports. Bob's uncle, Charles Kalsu, played basketball at Oklahoma State for Henry Iba, whose legend in college hoops was writ as large as Wilkinson's was in football. The 6'6" Charles was a second-team All-America in 1939 and played pro ball with the old Philips 66 Oilers. Charles's brother Frank Kalsu, three inches shorter and two years younger, yearned to follow him to Oklahoma State. "Frank and Charles were extremely competitive," recalls their younger brother, Milt. "Frank went to Stillwater thinking he could play, lie lasted half a semester and came home." Frank married Leah Aguillard, of French Canadian ancestry, became a sheet-metal worker at Tinker Air Force Base in Midwest City, Okla., and settled in Del City.
Frank saw in his son, Bob, an open-field run at fulfilling the dreams that he had left behind in Stillwater. "That's what made him drive his son to be a college athlete," Milt says. "He'd wanted to play basketball for Iba." Frank put the teenage Bob on a rigorous conditioning program long before such regimens were common. Milt still remembers Bob chuffing through four-mile cross-country runs among the tumbleweed and jackrabbits while Frank trailed behind him in the family car.
Early on, the boy began to live for the playing of games, for competition, and he approached everything as if it were a last stand. "He played every kind of ball imaginable," says Leah. "He was even on a bowling team. He loved to play cards—canasta, hearts. We'd play Chinese checkers head-to-head. We played jacks when he was seven or eight. He played jacks until he was in high school. He'd never quit when he lost. He'd say, 'Mom, let's play another.' "
