On July 22, 1861, Brigadier-General Cobb ordered a court martial to convene at the armory of the City Guard for the trial of lieutenants Ducroynell and Gailhard, and such other officers of the French Guard that may be brought before it. The officers named were from the Carbineers, and their offense consisted of their refusal to recognize Eugene Villargne as captain. The lieutenants contended the captain had resigned and his resignation had been accepted, therefore, he had no authority over them. (San Francisco Daily Herald, July 22, 1861, page 1, column 1.) No records are available that would reveal what the outcome of the court martial was, but the Adjutant General's Report of 1862 shows that the then Lieutenant Gailhard had been elected captain of the Carbineers, succeeding E. Villargne, so it seemed likely he was acquitted at the trial. Since the Adjutant General's Report of 1863 does not list the Carbineers as a unit in the militia at that date, it is assumed that the dissension caused by the court martial so weakened the company numerically that it was ordered disbanded in the latter part of 1862.
