The Battle of Tepic was an engagement during the Mexican Revolution where two formers allies Emil Lewis Holmdahl and Martín Espinosa, turned enemies fought for control over the provincial capital of Tepic.

They refused and then wisely fled to the mountains, from where they joined 280 Cora Indians loyal to Madero.

Holmdahl, the seven officers, and the Indians attacked Tepic, armed with bows and arrows and an old brass cannon.

After 36 hours of fighting, Holmdahl's forces were defeated with 2/3 of their men dead including all seven officers.

Espinosa on the otherside would later loose tepic, be exiled by Victoriano Huerta, and later assassinated.
