The Los Angeles Greys was organized on February 1, 1861, after having filed the usual petition with the County Judge and meeting all requirements. of the State Laws. H. N. Alexander was elected Captain and I. F. Bostwick, First Lieutenant.
The company was one of the fortunate units that received their arms and equipment with very little delay. Adjutant General Kibbe stated that this company was well drilled, very efficient and armed with rifled muskets. He further indicated however, that Captain Alexander had failed to comply with the law of the State in making returns of his company, although having been requested to do so by the Adjutant General's office.
The reason for the failure to send the returns was made clear, when Governor Downey received a letter from Captain Alexander dated December 1, 1861, stating that he had been unable to get his men to drill or attend meeting for three months, and asked permission to resign his commission as Captain. He expressed the opinion that the organization would not continue as a unit, all therefore, the Bondsmen desired to turn the company's arms and accoutrements back to the State.
The Los Angeles Greys were probably disbanded in 1862, as no further records could be found concerning the company subsequent to that date.
