Relatives, friends and admirers by the dozen gathered in Oyster Bay last night at a wake for war correspondent and Long Island native Marie Colvin.

The Sunday Times of London veteran journalist was killed Feb. 22 in an apparent attempt by the Syrian government to stop her from covering its slaughter of civilians.

“She died doing what she loved [and] will be terribly missed. We’ve known her since third grade,” said Ann Dick, on hand with her daughter, Margaret.

A portrait of Colvin — painted by a Sri Lankan artist in honor of the journalist, who lost an eye while bravely covering Sri Lanka’s civil war — stood near the entrance to the Oyster Bay Funeral Home.

The closed casket was adorned with red and white roses. Near it sat a scrapbook of her work, including an interview with Moammar Khadafy.

A video slide show of her life and work was also played.

Killed with Colvin when Syria shelled a makeshift media center was French photographer Jean-Pierre Perrin.

Meanwhile, the Sunday Times reported the British government has ordered an investigation into Colvin’s death.

William Hague, the foreign secretary, has ordered the probe as part of a larger effort to build a case against Syrian dictator Bashar al-Assad for war crimes.
