To spare us needless time and effort, read the law yourself. There had been no earlier qualification regarding race. Creoles and other free persons of color belonged to the militia because they were citizens under the Treaty of Paris, Apr 30, 1803. The militia law of Jan 23, 1862, extended enrollment to include residents, not just citizens, but restricted it to white males. In response European men living in New Orleans and surrounding parishes organized the European Brigade of Louisiana militia.

For reference see John D Winters, The Civil War in Louisiana, p 72, a Google book.

The Native Guards are not listed among the regiments and battalions named by Art Bergeron, nor were they part of the European Brigade. They did not go to Camp Moore with other Louisiana militia commands after the fall of New Orleans.
