    Wakiva 86k Alcedo, left center, and USS Wakiva II (SP 160), at right picking up survivors in 1917. This photograph was probably taken on 28 October 1917, when these two converted yachts picked up men who had left the torpedoed transport Finland. The two-stacked ship in the center distance, beyond Alcedo's bow, appears to have four masts and is probably Finland, which survived the incident and later served as USS Finland (ID 4543)
