On the afternoon of April 21st, was placed in charge of a small squad of men and stationed at the corner of a warehouse to eastward of the custom house. His position was subject to a severe fire from the buildings along Avenida Inadero y Cos, and after several hours of well directed fire he silenced it. On April 22d when a general advance began, he was sent ahead to locate and silence fire from snipers. Being an excellent marksman and notably cool, he was especially selected for this work. Later, when two sections of artillery were sent to join Captain Anderson's command, he performed similar services and was almost continually under direct fire from snipers. His services in this connection were of more value than a whole squad.
