LOUISVILLE, KY. — A soldier who fled to Canada rather than accept a second tour in Iraq turned himself over to military authorities at Fort Knox yesterday, his attorney said.

A former combat engineer, Kyle Snyder, left America in April 2005 while on leave. He said he worked as a welder and at a children’s health clinic in Canada.

Mr. Snyder’s lawyer, James Fennerty, said he had reached a deal with Army officials to allow Mr. Snyder to be processed back into uniform at Fort Knox, southwest of Louisville, and then be discharged. But he said Mr. Snyder told him yesterday afternoon that the Army wants to send him back to his original unit at Fort Leonard Wood, Mo., where commanders would determine his future.

“We wouldn’t have brought him back here if we knew this was going to happen,” Mr. Fennerty said.

A Fort Knox spokeswoman, Gini Sinclair, said she could not comment on Mr. Snyder’s case but said deserters whose units are not fully deployed are returned to that unit.

A Fort Leonard Wood spokesman, Mike Alley, said Mr. Snyder was scheduled to be processed there but that he had no details.

Mr. Snyder, 23, of Colorado Springs, Colo., was trained as an engineer with the 94th Corps of Engineers but said that when he was sent to Iraq in 2004, he was put on patrol, something he said he wasn’t trained to do.

He said he began to turn against the war when he saw an innocent Iraqi man seriously wounded by American gunfire.
