German citizenship heals old wounds.

More than six decades after his birth, the son of a French mother and a German Wehrmacht officer, retiree Daniel Rouxel was on Wednesday at last granted German citizenship.

The 66-year-old feels that by becoming a dual French-German national he finally has a legitimate identity.

"I'm German. I'm not a bastard any more. I'm a child like all the others. At last I've got the second half that I was so cruelly missing," he said, blinking back tears after leaving the German consulate in Paris.

Rouxel was born in Paris in 1943 during the World War II occupation, when his mother was working in the canteen of the German airbase in the Brittany town of Pleurtuit where his father, Lieutenant Otto Ammon, was stationed.

Ammon was killed during the Allied liberation of France and after the war, when his mother could no longer cope with raising him, Rouxel was taken on by his grandmother and moved to a small and unwelcoming Breton village.

"I'm the child born of a love made impossible by war," he said, in a recent account of his life written in support of his citizenship bid.

As the illegitimate son of the former enemy, Rouxel was a figure of hate, tormented by local youths, often forced by his own grandmother to sleep in a henhouse and publicly mocked by local officials.

Neither German nor French officials in the period after the war wanted to address the issue of children born to occupying troops, who might number up to 200,000 according to writers Jean-Paul Picaper and Ludwig Norz.

Officially registered as "father unknown" they have been subjected to years of ostracism and persecution, and the countries -- now close allies -- recently reached an agreement to recognise the children's parentage.

Germany agreed on February 19 to grant joint citizenship to those war children who want it, and Rouxel -- who has been a vocal representative of the group, even though he cannot speak German -- was the first to sign up.
