Cecilio Chi, the native leader of Tepich, along with Jacinto Pat attacked Tepich on 30 July 1847, in reaction to the indiscriminate massacre of Mayas, ordered that all the non-Maya population be killed. By spring of 1848, the Maya forces had taken over most of the Yucatán, with the exception of the walled cities of Campeche and Mérida and the south-west coast, with Yucatecan troops holding the road from Mérida to the port of Sisal. The Yucatecan governor Miguel Barbachano had prepared a decree for the evacuation of Mérida, but was apparently delayed in publishing it by the lack of suitable paper in the besieged capital. The decree became unnecessary when the republican troops suddenly broke the siege and took the offensive with major advances.
