Part 2 The Division Azul, the blue division.
Although Francesco Franco tried to be neutral during WW 2 he several times halfheartedly offered to join the Axis, Germany and Italy.
But basically Spain was still recovering from the devastating Civil war just a few years earlier. This Civil war was won by the Nationalist Falange party with the material and financial help of Fascist Italy and Nazi Germany.
To partly pay of his debts to Germany, Franco offered Spanish volunteer troops under the condition that they only would fight on the Eastern front against Bolshevism (Russian Communists). These volunteers were trained in Germany before being send to the front. A total of some 45,000 Spanish volunteered on the Russian front and some 4,500 perished. These Spanish troops were instrumental in the siege of Leningrad.
On the card is written VIVA LA DIVISION, meaning long live the division (Azul division)
There are multiple sensor marks on the card.
The large blue rectangle is a Spanish military sensor mark stamped in Sevilla, southern Spain.
There are 2 German Wehrmacht (?) handstamps with the part of the Feldpost 25C readable. Feldpost= Field Post.
There are some other marks on the postcard not yet deciphered by me.
