Among the spectators, there was a gasp, and one woman put her hands up, covering her face.
"I'm shocked. I did not think she would do that," said Manning supporter Jim Holland, of San Diego. "Thirty-five years, my Lord."
The former intelligence analyst was found guilty last month of 20 crimes, including six violations of the Espionage Act, as part of the Obama administration's unprecedented crackdown on media leaks.
But the judge acquitted him of the most serious charge, aiding the enemy, an offense that could have meant life in prison without parole.
Manning, 25, could have gotten 90 years behind bars. Prosecutors asked for at least 60 years as a warning to other soldiers, while Manning's lawyer suggested he get no more than 25, because some of the documents he leaked will be declassified by then.
Manning will get credit for the more than three years he has been held, but he'll have to serve at least one-third of his sentence before he is eligible for parole. His rank was reduced to private, he was dishonorably discharged and he forfeited his pay.
Before announcing the sentence, Lind warned spectators against any outbursts, saying she would stop the proceedings and expel anyone creating a disturbance, as she has in the past.
She had barely stepped out of the room when guards hurried Manning out through a front entrance and some half-dozen supporters shouted from the back of the room: "We'll keep fighting for you, Bradley" and "You're our hero."
The native of Crescent, Okla., digitally copied and released more than 700,000 documents, including Iraq and Afghanistan battlefield reports and State Department cables, while working in 2010 in Iraq.
He also leaked video of a 2007 Apache helicopter attack in Baghdad that mistakenly killed at least nine people, including a Reuters photographer.
A potentially more explosive leak case unfolded as Manning's court-martial was underway, when former National Security Agency contractor Edward Snowden was charged with espionage for exposing the NSA's Internet and telephone surveillance programs.
At his trial, Manning said he gave the material to the secrets-spilling website WikiLeaks to expose the U.S. military's "bloodlust" and generate debate over the wars and U.S. policy.
During the sentencing phase, he apologized for the damage he caused, saying, "When I made these decisions, I believed I was going to help people, not hurt people."
His lawyers also argued that Manning suffered extreme inner turmoil over his gender identity — his feeling that he was a woman trapped in a man's body — while serving in the macho military, which at the time barred gays from serving openly. Among the evidence was a photo of him in a blond wig and lipstick.
Defense attorney David Coombs told the judge that Manning had been full of youthful idealism.
"He had pure intentions at the time that he committed his offenses," Coombs said. "At that time, Pfc. Manning really, truly, genuinely believed that this information could make a difference."
Prosecutors did not present any evidence in open court that anyone was physically harmed as a direct result of Manning's actions. But they showed that al-Qaida used material from the helicopter attack in a propaganda video and that Osama bin Laden presumably read some of the leaked documents, which were published online by WikiLeaks. Some of the material was found in bin Laden's compound when it was raided.
Also, government witnesses testified the leaks endangered U.S. intelligence sources, some of whom were moved to other countries for their safety. And several ambassadors were recalled, expelled or reassigned because of embarrassing disclosures.
Prosecutors called Manning an anarchist and an attention-seeking traitor, while supporters have hailed him as a whistle-blower and likened him to Daniel Ellsberg, the defense analyst who in 1971 leaked the Pentagon Papers, a secret history of U.S. involvement in Vietnam, to the New York Times and other newspapers.
That case touched off an epic clash between the Nixon administration and the press, and led to a landmark U.S. Supreme Court ruling on the First Amendment.
The Obama administration has charged seven people with leaking to the news media, while only three people were prosecuted in all previous administrations combined.
Among those seven is Snowden, whose leak has triggered a fierce debate over security vs. privacy and strained U.S. relations with Russia, which is harboring him despite demands he be returned to this country to face charges.
In addition, the Justice Department has obtained the records of phones used by Associated Press journalists and emails of a Fox News reporter.
Also, a federal appeals court ruled recently that New York Times reporter James Risen cannot shield his source when he testifies at the trial of a former CIA officer accused of leaking information about a secret operation.
Michael Ratner, a lawyer for WikiLeaks founder Julian Assange, has suggested Manning's conviction could make it easier for federal prosecutors to get an indictment against Assange as a co-conspirator.
