U.S.S. Stingray: Sunk, Or Not Sunk?

FRI 21 APR 1944
Pacific
TF 58 (Vice Admiral Marc A. Mitscher), including carriers, battleships, cruisers, and destroyers, bombs and bombards Japanese airfields and defensive positions at Hollandia, Wakde, Sawar, and Sarmi areas of New Guinea; attacks continue the following day in preparation for Operations PERSECUTION and RECKLESS (see 22 April 1944). During these operations, Japanese army cargo ship Kansei Maru is sunk by aircraft off Sarmi. Navy aircraft sink small Japanese cargo vessels No.51 Ume Maru and No.2 Hihode Maru, Mapia Island, New Guinea.

Submarine Stingray (SS-186) is sunk when she strikes submerged pinnacle west of the Marianas, 20°30'N, 142°22'E. [The sinking (& the date) are debatable, at the very least, if one trusts Wikipedia. Or, from the horse's mouth, p. 8 of the Stingray's 10th war patrol report. P. 220 here. — M.B.]

Japanese cargo vessel No.2 Y_ei [sic] Maru is sunk by aircraft off Murilo Island, Carolines.

Mediterranean
U.S. freighter John Armstrong is damaged by mine at 41°12'N, 12°32'E, while en route from Anzio to Naples, Italy. One Armed Guard sailor perishes in the incident, but the ship reaches her original destination unaided.
