On April 9, 1914, Soledad Casilda Hernáez Vargas was born to a single mother in Zizurkil, Gipuzkoa. In the 1930s she became a well-known feminist political activist and anarchist militant in Gipuzkoa, taking an active part in fighting at the outbreak of the Spanish Civil War as well as later in the French Resistance against the Nazi occupation of France.
Subsequently known as Kasilda, Kaxilda, Kasi, or “la Miliciana,” she was raised in Donostia-San Sebastián in a Bohemian family with strong connections to the anarchist movement. As a young woman in the early 1930s she caused a scandal by bathing nude on the Zurriola Beach in Donostia. Becoming an activist in the anarchist movement, she was arrested in 1934 for distributing propaganda and possessing explosives during the revolutionary strike of October that year. She was, though, released in 1936 as part of a general amnesty conceded by the newly elected Popular Front coalition government in Madrid. On leaving prison prison, she met fellow Basque anarchist activist Felix Likiano (1909-1982), her partner for the rest of her life.
When the Civil War broke out in July 1936, she joined Likiano in the anarchist militia formed to defend Donostia against the attack of the rebel troops, seeing active service in the Battle of Irun (Aug. 27 – Sep. 5, 1936) and, later, after the fall of her home city, also as part of the Hilario-Zamora Column on the Aragon and Ebro Fronts in 1938. With the triumph of the rebels, however, she and Likiano fled to France, where they were subsequently arrested and sent to the Argelès-sur-Mer and Gurs concentration camps. Released in 1940, the couple then moved first to Baiona in Lapurdi, but ultimately settled in Bordeaux, where their home–nicknamed the “Basque Consulate”–became a well-known meeting place for exiled Spanish Republicans. With the Nazi occupation of France they collaborated actively with the French Resistance.
After a spell in Paris, they returned to the Basque Country, settling in Biarritz. She died in 1992 and on her gravestone one can read the inscription “Andra! Zu zera bukatzen ez den sua!” (Woman! You’re the fire that never goes out!).
