Very nice find Jose.

Here is a picture from the Library of Congress that appears to show the gentleman in question seated second from left in the front row. This picture is titled "US Army Officers in Mindanao and Sulu Region 1899-1902."

Seated center could be Major General Leonard Wood, which would date this picture to 1903–1905. Van Orsdale and Wood both arrived in Cotabato in August, 1903. Van Orsdale left Mindanao August, 1905 and returned to the US.
