↑ Số lượng thương vong vẫn còn đang tranh cãi; ước tính có khoảng từ 500.000 đến một triệu người hy sinh. Trong nhiều năm, các nhà sử học cố giữ cho con số thiệt hại ở mức nhỏ nhất và các nghiên cứu gần đây kết luận rằng 500.000 là chính xác.

↑ The statistics on assassinations, destruction of religious buildings, etc. immediately before the start of the war come from The Last Crusade: Spain: 1936 by Warren Carroll (Christendom Press, 1998). He collected the numbers from Historia de la Persecución Religiosa en España (1936–1939) by Antonio Montero Moreno (Biblioteca de Autores Cristianos, 3rd edition, 1999)

Condés was a close personal friend of Castillo. His squad had originally gone looking to arrest Gil Robles as a reprisal for Castillo's murder, but when Robles was not at home they went to the house of Calvo Sotelo. Thomas concluded that the intention of Condés was to arrest Calvo Sotelo and that Cuenca acted on his own initiative, although he acknowledges other sources that dispute this finding. Cuenca and Condés were both killed in action in the first Rebel offensive against Madrid shortly after the start of the war.
