 This tension was increased slightly when Valois brought his squadron into San Francisco on 4 June 1891 without the expected courtesy of raising an American flag.Perhaps it was for this reason that Admiral Andrew E. K. Benham, commander of Mare Island Station did not visit Valois.This was during the 1891 Chilean Civil War and he was soon ordered south where, along with US and British navies, he was involved in the search for the gun-running Chilean ship "Itata" (Itata Incident).
