NEW ORLEANS — Soldiers coaxed some of Hurricane Katrina's stubborn holdouts from their homes Wednesday after the mayor ordered all 10,000 or so residents still in this ruined city evacuated — by force, if necessary — because of the risk of fires and disease.

"I haven't left my house in my life. I don't want to leave," said a frail-looking 86-year-old Anthony Charbonnet, shaking his head as he locked his front door and walked slowly backwards down the steps of the house where he had lived since 1955.

Charbonnet left only after a neighbor assured him: "Things will be OK. It'll be like a vacation." Still protesting, Charbonnet stepped into the ambulance in which soldiers from the Army's 82nd Airborne Division would take him to a helicopter.

As floodwaters began to slowly recede with the first of the city's pumps returning to operation, Mayor C. Ray Nagin instructed law enforcement officers and the U.S. military late Tuesday to evacuate all holdouts for their own safety. He warned that the fetid water could spread disease and that natural gas was leaking all over town.

As of midday Wednesday, there were no reports of anyone being removed by force.

"We have thousands of people who want to voluntarily evacuate at this time," Police Chief Eddie Compass said. Once they all are out, he said, "then we'll concentrate our forces on mandatory evacuation."

The stepped-up evacuation came as workers struggled find and count the corpses decaying in the 90-degree heat. Even when cadaver dogs pick up a scent, workers frequently cannot get at the bodies without heavy equipment. The mayor has estimated New Orleans' death toll could reach 10,000.

The enormity of the disaster became ever-clearer: State Rep. Nita Hutter said 30 people died at a flooded-out nursing home in Chalmette, just outside New Orleans. She said the staff left the elderly residents behind in their beds. And more than 100 people died at a dockside warehouse, waiting for rescuers to ferry them to safety, said Rep. Charlie Melancon, whose congressional district includes the area.

Meanwhile, firefighters battled blazes around New Orleans — an emerging threat in a city where the water pressure is too low to fight fires and where many people are using candles because of the lack of electricity. At the same time, workers returning to restart essential services came under sniper fire.

"We have got some information where, some possible shooters have been shooting at some employees trying to get in to the city to actually get it back up and running," police Sgt. Charlie Smith said.
