Cpl. Christopher Jonathan Reid, with the 1st Battalion of the Princess Patricia's Canadian Light Infantry, was killed in action.

He died on Aug. 3 in an area where Canadian soldiers have been advancing on Taliban insurgents, said Col. Tom Putt, deputy commander of Task Force Afghanistan.

Reid was the 20th soldier to be killed since Canadians moved into Afghanistan in 2002, and the 12th to die in the last six months.

Reid, based in Edmonton, died during the night when a Canadian Light Armoured Vehicle, or LAV-3, was struck by a roadside bomb.

TRURO, N.S. Angela Reid says that when she spoke with her son for the last time, he was in a great mood and showed no sign of growing tired of his mission in Afghanistan even though he was slated to return to Canada within weeks.

In a brief phone call Wednesday, Reid says she urged her son to remain on high alert as he traversed the dangerous terrain.

But when a military padre came knocking at her door at 4 a.m. yesterday, Reid knew her warnings had not saved him.

Officials informed her that their only remaining child, Cpl. Christopher Reid, was one of four Canadian soldiers killed in attacks yesterday near Kandahar.
