By this circular letter Sierra y Rosa announces the Polkos Revolt, which had broken out on this day in Mexico City. He states, however, that some units have remained loyal to the government and that those participating in the revolt are disloyal to the country. The revolt prevented any relief from reaching Veracruz in time to stop Scott. This is the earliest announcement of the revolt.
