Retired Army Gen. Alexander Haig, who held influential positions in the U.S. military and government and who as White House chief of staff shepherded Richard M. Nixon toward peacefully resigning the presidency, died Saturday at Johns Hopkins Hospital in Baltimore of complications from an infection. He was 85. 
 
 Presidents Gerald R. Ford and Jimmy Carter sent the four-star general to Europe as supreme commander of NATO. Ronald Reagan made him secretary of state, a brief and stormy appointment in which he famously tried to assert command after the attempted assassination of the president. And Gen. Haig himself, a tall man with blue eyes who kept his chin-up military bearing long after he left the service, ran for the Republican presidential nomination in 1988. 
 
 In a statement, President Obama said Gen. Haig "exemplified our finest warrior-diplomat tradition of those who dedicate their lives to public service." 
 
 Gen. Haig's influence peaked in his late 40s, during Nixon's last 16 months in office, when brewing developments in the Watergate scandal damaged and increasingly distracted the president. Secretary of State Henry Kissinger famously told Gen. Haig to keep the country together while he held the world together during one of the greatest constitutional crises in the nation's history. Special prosecutor Leon Jaworski, and many others, called Gen. Haig the "37 1/2 president." 
 
 Gen. Haig, untainted by the botched break-in at the Democratic National Committee headquarters, took over as chief of staff in May 1973 from H.R. "Bob" Haldeman, who would spend 18 months in prison for his role in the Watergate scandal. When the public learned about the secret Oval Office taping system, which would eventually implicate Nixon in the coverup, Gen. Haig, as he acknowledged later, urged the president to destroy the tapes. 
 
 When Watergate special prosecutor Archibald Cox, Jaworski's predecessor, pursued his investigation too aggressively for Nixon's comfort, the president dispatched Gen. Haig in October 1973 to instruct the acting attorney general, William D. Ruckelshaus, to fire Cox. "Your commander in chief has given you an order," Gen. Haig told him. 
 
 Ruckelshaus refused, quitting instead in what became known as the Saturday Night Massacre. 
 
 Although Gen. Haig vigorously defended the president, he realized the direness of the mounting evidence and arranged a series of meetings between Nixon, his attorneys and leading members of Congress to make Nixon understand that his position had become untenable in the summer of 1974. 
 
 Gen. Haig said he thought Nixon needed to make the final decision, but he "smoothed the way" by presenting resignation as the only serious option, according to the account of this period in journalists Bob Woodward and Carl Bernstein's 1976 book "The Final Days." After the president broached the possibility of suicide, the authors noted, Gen. Haig ordered doctors to take away Nixon's tranquilizers and deny his requests for pills. 
 
 Then, on Aug. 1, 1974, Gen. Haig told Vice President Ford that he should prepare to assume the presidency. Critics said later that he brokered a deal that got Nixon a pardon in exchange for stepping down. Gen. Haig maintained that he never implicitly or explicitly made such an offer. 
 
 Gen. Haig stood on the White House lawn eight days later, on Aug. 9, when Nixon left town. The chief of staff had his arms folded, but he discreetly gave a thumbs-up to his disgraced boss. 
 
 Powerful mentors 
 
 
 
 Alexander Meigs Haig Jr. was born on Dec. 2, 1924, in the Philadelphia suburb of Bala Cynwyd, Pa. He was 10 when his father, a lawyer, died of cancer and left the family $5,000 in life insurance money. Gen. Haig was the second of three children, but he assumed an important role in family matters as the oldest male. ||||| Seven years before, Mr. Haig really had been in control. He was widely perceived as the acting president during the final months of the Nixon administration. 
 
 He kept the White House running as the distraught and despondent commander in chief was driven from power by the threat of impeachment in 1974. “He was the president toward the end,” William B. Saxbe, the United States attorney general in 1974, was quoted as saying in “Nixon: An Oral History of His Presidency” (HarperCollins, 1994). “He held that office together.” 
 
 Henry A. Kissinger , his mentor and master in the Nixon White House, also said the nation owed Mr. Haig its gratitude for steering the ship of state through dangerous waters in the final days of the Nixon era. “By sheer willpower, dedication and self-discipline, he held the government together,” Mr. Kissinger wrote in the memoir “Years of Upheaval.” 
 
 Mr. Haig took pride in his cool handling of a constitutional crisis without precedent. 
 
 “There were no tanks,” he said during a hearing on his nomination as secretary of state in 1981. “There were not any sandbags outside the White House.” 
 
 Serving the Nixon White House from 1969 to 1974, Mr. Haig went from colonel to four-star general without holding a major battlefield command, an extraordinary rise with few if any precedents in American military history. 
 
 But the White House was its own battlefield in those years. He won his stars through his tireless service to President Richard M. Nixon and Mr. Nixon’s national security adviser, Mr. Kissinger. 
 
 Mr. Haig never lost his will. But he frequently lost his composure as Mr. Reagan’s secretary of state. As a consequence, he lost both his job and his standing in the American government.

 Mr. Nixon had privately suggested to the Reagan transition team that Mr. Haig would make a great secretary of state. Upon his appointment, Mr. Haig declared himself “the vicar of foreign policy” — in the Roman Catholic Church , to which he belonged, the pope is the “vicar of Christ” — but he soon became an apostate in the new administration. 
 
 He alienated his affable commander in chief and the vice president, George H. W. Bush , whose national security aide, Donald P. Gregg, described Mr. Haig as “a cobra among garter snakes.” 
 
 Mr. Haig served for 17 months before Mr. Reagan dismissed him with a one-page letter on June 24, 1982. 
 
 Those months were marked by a largely covert paramilitary campaign against Central American leftists, a heightening of nuclear tensions with the Soviet Union, and dismay among American allies about the lurching course of American foreign policy. 
 
 Sixteen months after his departure came the deaths of 241 American Marines , sailors and soldiers in a terrorist bombing in Beirut and, two days later, the American invasion of the Caribbean nation of Grenada . 
 
 “His tenure as secretary of state was very traumatic,” John M. Poindexter , later Mr. Reagan’s national security adviser, recalled in the oral history “Reagan: The Man and His Presidency” (Houghton Mifflin, 1998). “As a result of this constant tension that existed between the White House and the State Department about who was going to be responsible for national security and foreign policy, we got very little done.” 
 
 Mr. Haig said the president had assured him that he “would be the spokesman for the U.S. government.” But he came to believe — with reason — that the White House staff had banded together against him. 
 
 He blamed in particular the so-called troika of James A. Baker III , Edwin Meese III and Michael K. Deaver.

 “Reagan was a cipher,” Mr. Haig said with evident bitterness. “These men were running the government.” 
 
 He reflected: “Having been a White House chief of staff, and having lived in the White House under great tension, you know that the White House attracts extremely ambitious people. Those who get to the top are usually prepared to go to extraordinary lengths to get there.” 
 
 Mr. Haig briefly considered running for president in 1980 and became a candidate in 1988, but his campaign attracted virtually no popular support. 
 
 A spokesman for Johns Hopkins, Gary Stephenson, said Mr. Haig’s death was caused by staphylococcal infection that he had before his admission to the hospital. Mr. Haig is survived by his wife, the former Patricia Fox, 81; their three children, Alexander Patrick Haig Sr. and Barbara Haig, both of Washington, and Brian Haig of Hopewell, N.J.; and eight grandchildren, according to the Rev. Frank Haig, 81, his brother and a professor emeritus of physics at Loyola University Maryland in Baltimore.

 Father Haig said the Army was coordinating a Mass at Fort Myer in Washington and an interment at Arlington National Cemetery, but both would be delayed by about two weeks due to the wars in Afghanistan and Iraq . 
 
 In a statement issued Saturday, President Obama said: “Today we mourn the loss of Alexander Haig, a great American who served our country with distinction. General Haig exemplified our finest warrior-diplomat tradition of those who dedicate their lives to public service.” 
 
 Alexander Meigs Haig Jr. was born in Philadelphia on Dec. 2, 1924, the son of a lawyer and a homemaker. At 22, he graduated from West Point , ranking 214th of 310 members of the class of 1947.

 As a young lieutenant, he went to Japan to serve as an aide to Gen. Alonzo P. Fox, deputy chief of staff to Gen. Douglas MacArthur, the supreme allied commander and American viceroy of the Far East. 
 
 In 1950, Mr. Haig married the general’s daughter. 
 
 Introduction to War 
 
 Mr. Haig’s first taste of war was brutal. In the first months of the Korean War, he served on the staff of Maj. Gen. Edward M. Almond, chief of staff of the Far Eastern Command. Official Army histories depict General Almond as a terror to his underlings and as one of General MacArthur’s most uncompromising disciples.

 Following orders, General Almond sent thousands of American soldiers north toward the Chinese border in November 1950. They met a ferocious surprise counterattack from a far larger Chinese force. 
 
 General Almond and Lieutenant Haig flew to the forward outpost of an American task force on Nov. 28, where the general pinned a medal on a lieutenant colonel’s parka, told him the Chinese were only stragglers, and then flew off. Of that task force, once 2,500 strong, some 1,000 were killed, wounded, captured or left to die. In all, within two weeks, American forces in Korea took 12,975 casualties, in one of the worst routs in American military history. 
 
 After the Korean War, the young officer served at the Pentagon and eventually become a deputy special assistant to Secretary of Defense Robert S. McNamara . He served in Vietnam in 1966 and 1967 as a battalion and brigade commander of the First Infantry Division, and received the Distinguished Service Cross. 
 
 In 1969, Colonel Haig became a military assistant on the staff of Mr. Kissinger’s National Security Council . He distinguished himself as the hardest worker in an ambitious and talented cohort. Soon he was a brigadier general and Mr. Kissinger’s deputy. 
 
 Vietnam consumed General Haig. He made 14 trips to Southeast Asia from 1970 to 1973. He later said that Mr. Kissinger “got snookered” in negotiations with the enemy, and that he would have chosen to be more forceful. “That is how Eisenhower settled Korea,” Mr. Haig said. “He told them he was going to nuke them. In Vietnam, we didn’t have to use nuclear weapons; all we had to do was to act like a nation.” 
 
 Then Watergate consumed the White House. In 1973, after a brief stint as the Army’s vice chief of staff, General Haig was summoned back as chief of staff, replacing H. R. Haldeman, who later went to prison. 
 
 All this, in the course of a few weeks in the fall of 1973, fell on Mr. Haig’s head: 
 
 Vice President Spiro T. Agnew pleaded no contest to taking bribes. The next man in line under the Constitution, House Speaker Carl Albert, was being treated for alcoholism . The president himself, by some accounts, was drinking heavily. War broke out in the Middle East . When the president tried to fire the Watergate special prosecutor, Archibald Cox , rather than surrender his secret White House tapes, the attorney general, Elliot L. Richardson, and his deputy, William D. Ruckelshaus, resigned. Impeachment loomed. 
 
 What began with the arrest of several men breaking into Democratic headquarters at the Watergate complex in Washington in June 1972 had poisoned the presidency. Days after the break-in, the president and his closest aides had discussed how to cover up their role and how to obtain hush money for the burglars. The discussions, secretly taped by the president, were evidence of obstruction of justice.

 General Haig was one of the first people, if not the very first person, to read transcripts of the tapes the president had withheld from the special prosecutor. “When I finished reading it,” he says in “Nixon: An Oral History,” “I knew that Nixon would never survive — no way.” 
 
 On Aug. 1, 1974, the general went to Vice President Gerald R. Ford and discussed the possibility of a pardon for the president. Mr. Nixon left office a week later; the pardon came the next month. Public outrage was deep. Mr. Haig soon departed. 
 
 After leaving the White House in October 1974, he became supreme allied commander in Europe , the overseer of NATO . In 1979, he resigned and retired from the Army. He served for a year as president of United Technologies . 
 
 A “Haig for President” committee was formed but dissolved in 1980. Mr. Haig made a full-fledged run for the Republican nomination in 1988. But he placed last among the six Republican candidates in Iowa , where he barely campaigned, and he withdrew before the New Hampshire primary. He had been, he said, “the darkest of the dark horses.” 
 
 In his 80s, Mr. Haig ran Worldwide Associates, a firm offering “strategic advice” on global commerce. He also appeared on Fox News as a military and political analyst. 
 
 His Way With Words 
 
 He had a unique way with words. In a 1981 “On Language” column, William Safire of The New York Times , a veteran of the Nixon White House, called it “haigravation.” 
 
 Nouns became verbs or adverbs: “I’ll have to caveat my response, Senator.” (Caveat is Latin for “let him beware.” In English, it means “warning.” In Mr. Haig’s lexicon, it meant to say something with a warning that it might or might not be so.) 
 
 Haigspeak could be subtle: “There are nuance-al differences between Henry Kissinger and me on that.” It could be dramatic: “Some sinister force” had erased one of Mr. Nixon’s subpoenaed Watergate tapes, creating an 18 1/2- minute gap. Sometimes it was an emblem of the never-ending battle between politics and the English language: “careful caution,” “epistemologically-wise,” “saddle myself with a statistical fence.”

 But he could also speak with clarity and conviction about the presidents he served, and about his own role in government. Mr. Nixon would always be remembered for Watergate, he said, “because the event had such major historic consequences for the country: a fundamental discrediting of respect for the office; a new skepticism about politics in general, which every American feels.” 
 
 Mr. Reagan, he said, would be remembered for having had “the good fortune of having been president when the Evil Empire began to unravel.” But, he went on, “to consider that standing tall in Grenada, or building Star Wars, brought the Russians to their knees is a distortion of historic reality. The internal contradictions of Marxism brought it to its knees.” 
 
 He was brutally candid about his own run for office and his subsequent distaste for political life. “Not being a politician, I think I can say this: The life of a politician in America is sleaze,” he told the authors of “Nixon: An Oral History.” 
 
 “I didn’t realize it until I started to run for office,” he said. “But there is hardly a straight guy in the business. As Nixon always said to me — and he took great pride in it — ‘Al, I never took a dollar. I had somebody else do it.’ ”
– Alexander Haig died this morning at age 85. The former four-star general served as White House chief of staff during the tumultuous final months of the Nixon administration—he kept the place running and guided Nixon toward a peaceful resignation, reports the Washington Post—and he ran for the top office himself in 1988. But he's perhaps best known to Americans as Ronald Reagan's secretary of state, who incorrectly told the nation "I am in control here" after Reagan got shot. Another former Reagan aide, Lyn Nofgizer, said Haig knew that despite all his accomplishments, the third paragraph of his obituary would harp on that, notes the New York Times—in the third paragraph of its obituary. Prior to the news conference in which he made the declaration, Haig told fellow Cabinet members that the "helm is right here, and that means in this chair for now, constitutionally, until the vice president gets here." The Constitution, of course, disagrees, and Haig's words forever earned him the reputation as being hungry for power.
