Some bits of information.

I think this is a palace at Pokroskaya, which was the headquarters of the Blue Division during its time at the front of Leningrad

Under this garden the bodies of some members of the unit lie forever.
And for those who didn't know, in the Blue Division fought not only Spanish volunteers, but also Portuguese ones, as João Rodrigues Júnior, who was 26 years old then. He fought in the Nationalist side during the Spanish in the ' Foreign Legion ' in 1936. He joined the Blue Division in 1941. His reasons:
"It was when the war against Russia began. And I, that in the years of the war of Spain I started understanding what they are the Bolshevists, and his ideas in the mother land, decided to continue my life of legionario, fighting against them. When in Spain began the inscriptions for the campaign of Russia, I volunteered.
- Were in the Blue Division other Portuguese legionaries?
- Yes, approximately fifteen. But I think I'm the only one that still vive."
The source of this information is

Perhaps the more interesting testimony is the one done by Jaime de Assuncâo Graça, veteran of the SCW of 1936-39 and ex-member of the Blue Division. He joined the Spanish Legion with a group of approximately 45 Portuguese and that had the assent of Salazar, took part in the SCW and he mentions places: Talavera de la Reina Real, Cuesta de las Perdices , Madrid , Chamartin, Villaverde Bajo, where he was hurt by grapeshot and sent to a hospital in Logroñoo.
He mentionssome Portuguese officials, like Ricardo Espirito Santo and the Captain Botelho Moniz, who after the war went to for the north of Africa, first to Tetuán, then Larache, reaching the destination finally in 1939 in a billeting to five kms from Ceuta, assigned to the 9th bandera of the Legion. In June of 1.942 during a revision done by a sergeant, he remembers the name of another called Portuguese Francisco Leonardo Olinda and in this way he became a volunteer to Russia where he was until January 1943.
From Africa he went from San Sebastian to the barracks of the Blue Division in Germany to Hof. It was in the front of Leningrad, next to Pushkin when he was hurt for the first time by a bullet in the left leg and taken to the hospital. He was send to hospital at Riga, Latvia, where he was given a discharge of 15 days. After the war he returned to Portugal.
As far as I know, the Blue Division was sent to the Leningrad front on may 1942. I'll try to gather more info.
