CADENA, Trinidad Gareia de la (cah-day'-nah), Mexican soldier, born in Zacatecas in 1832; died 1 November, 1886. He became noted during the French invasion, fighting with success at the head of guerillas. When the republic was re-established, and Juarez reinstated as president, in 1867, Cadena was appointed governor of Zacatecas; but in 1872 he declared against Juarez, and for Diaz, revolting with 5,000 federal troops at San Luis Potosi. They were joined by the garrisons of Zacatecas and Aguascalientes, and at the head of 8,000 men Cadena attacked the Tololotlan bridge, near Guada-lajara, and then advanced upon that City to lay siege to it; but General Rocha forced him to give up his plan and retire to Lo de Ovejo. Here Cadena was defeated in a fierce battle, and fled with 700 horsemen toward the northern frontier. He took advantage of the amnesty proclaimed in February, 1872, but three years afterward again revolted against President Lerdo de Tejada and in favor of the plan of Tuxtepec, advocated by Diaz. He then led a band of guerillas at Zacatecas and Aguascalientes, and, in an encounter with the government troops, killed Col. Ordonez. On the final success of the revolutionary army, Cadena met Diaz at Lagos, and it is said that in their conference Diaz promised Cadena to support his candidacy for the presidency of the republic as soon as he should be in power; but he was only elected governor of Zacatecas, and Diaz openly supported Manuel Gonzalez's candidacy. In March, 1880, a party of masked men made an attempt against Cadena's life while he was going to his farm, fifteen miles from Zacatecas. He defended himself with his rifle, killed two of the assailants, and dispersed the others, without being hurt. This and other violent acts caused him to remove to the City of Mexico and retire temporarily from public life. But, being annoyed by the government of Diaz, he disappeared from the capital in the latter part of October, 1886, and on 1 November was taken prisoner with his secretary, and immediately shot by order of President Diaz, whose arbitrary action in this matter was severely criticized.
