A Bronx firefighter and National Guardsman who was honored four years ago for helping to rescue two people from a fire was killed in Iraq when his vehicle came under enemy attack. Another city firefighter was wounded in the attack.

Sergeant Christian Engeldrum, 39, a five-year Fire Department veteran and former police officer who served with Ladder Company 61 at Co-op City, was killed Monday near Baghdad, according to Mayor Bloomberg and Fire Commissioner Nicholas Scoppetta.

“As a firefighter, a police officer, and a decorated member of our military, there was no risk he wasn’t willing to take for his fellow New Yorkers and fellow Americans,” said Mr. Bloomberg.

Manhattan firefighter Daniel Swift, 24, also a National Guardsman, was riding in the vehicle with Engeldrum and suffered shrapnel wounds, according to city officials. Mr. Swift, a firefighter assigned to “El Barrio’s Bravest” at Ladder Company 43 at Harlem, was taken to Germany, where he is being treated and is expected to recover fully.

Engeldrum, a veteran of Operation Desert Storm who lived and worked at the Bronx, is the first city employee to be killed in Iraq, according to Mr. Bloomberg. Engeldrum, who was married with two sons, is among 135 American troops killed in Iraq this month, matching April as the deadliest month of the war, which began in March 2003.

“My deepest condolences go out to the Engeldrum family at this tremendous loss,” said Mr. Scoppetta. “Christian served his country well in the armed services, as a police officer and firefighter. His commitment to serving his country sets the example for all of us. He will be greatly missed by this department and by all who had the honor of knowing him.”

Engeldrum was awarded an FDNY unit citation for bravery when his company rescued two people on July 15, 2000.

Engeldrum joined the Army in 1986 and served in Operation Desert Storm in 1990. He was awarded the Southwest Asia Service Medal with Bronze Service, Army Good Conduct Medal, the National Defense Service Medal, and the Army Achievement Medal.

He left active duty service in 1991 and joined the Police Department, where he was assigned to the 47th Precinct at Eastchester, the Bronx. He joined the Fire Department in 1999 and had served at Engine Company 58 at Manhattan and Engine Companies 89 and 61 at the Bronx.

Firefighters who answered the phone at Ladder 61 declined to comment on Engeldrum’s death.
