Guernica or Gernika is a town in the Autonomous Community of the Basque Country, in Spain.
When the Spanish Civil War started in 1936, the leaders of Nazi Germany decided to support the Nationalists led by Generalísimo Francisco Franco. HYDRA was among the German units sent by Adolf Hitler to assist the Nationalists on the battlefield.
In April 1937, HYDRA's armored vehicles and soldiers equipped with powerful exo-skeleton battle suits destroyed the city of Guernica. At the time, it was believed the German air force, the Luftwaffe, was responsible for the destruction of the city.
