The most notable of these occurred in Jayuya in what became known as "El Grito de Jayuya" (Jayuya Uprising). Nationalist leader Blanca Canales led the armed nationalists into the town and attacked the police station. A small battle with the police occurred; one officer was killed and three others were wounded before the rest dropped their weapons and surrendered. The nationalists cut the telephone lines and burned the post office. Canales led the group into the town square where the illegal light blue version of the Puerto Rican Flag was raised (it was against the law to carry a Puerto Rican Flag from 1898 to 1952.) In the town square, Canales gave a speech and declared Puerto Rico a free Republic. The town was held by the nationalists for three days.
