[3] In late 1914, he was the driving force of the moderate generals who wished to bring peace between the victorious Constitutional factions who began quarreling among themselves.

[8] At this time, Venustiano Carranza was the Maderist governor of Coahuila, and he advised Blanco to join the State militia.

Lucio Blanco was an early supporter of this revolt, and he received a commission as colonel in the Constitutional Forces.

In April 1913, Blanco had his first battlefield victory when he took the city of Aldamas, Tamaulipas, from forces loyal to Huerta.

[11] His most important triumph was the taking of the border city of Matamoros from federal troops on June 4, 1913, the first major victory of the Constitutionalists.

[12] Carranza promoted Blanco to the rank of brigadier general for having taken the city of Matamoros, but this early glory was short lived.

[13] In July 1913, Carranza appointed Pablo González commander the new department of the Northeast, bypassing Blanco.

[18] This action by Carranza prevented Blanco from becoming a national hero, alongside Francisco Villa and Emiliano Zapata.

He was at the forefront of all of Obregón’s victories and his principal accomplishments were the taking of the cities of Tepic and Guadalajara, the last one considered to be his greatest triumph after Matamoros.

“After all, Díaz’ only crime was growing old.”[21] Still, Blanco rode in alongside Obregón into Mexico City in August 1914 when Huerta and his government collapsed.

Blanco, being sympathetic to Zapata’s land reform program, gave orders for his forces to receive them cordially.

However, both Carranza and Obregón began to doubt his loyalty, and suspected that he would defect with his army and join Pancho Villa’s forces, and he fell out of favor.

Soon, Carranza considered him untrustworthy, and Blanco’s disagreements with Obregón escalated, especially as a result of his actions during the Convention of Aguascalientes in October.

Then in late January 1915, Blanco lost the support of Zapata because he refused to attack Pablo González at Querétaro.

[25] During the first half of 1915, Gutiérrez, Blanco and several other moderate generals attempted to govern independent of Carranza, Villa and Zapata, but the tide was against them.

Carranza was increasingly fearful that Obregón would turn against him, and he hoped that with Blanco’s support, the army would remain loyal.

There he joined with other exiles opposed to Obregón, and published pamphlets and conspired to start an armed revolt.
