Shooting up sampans: it wasn't all that easy

[LukeFF]

...as this report from the Pollack shows:

1222: Lat. 6d.-05'N; Long. 153d.-27.5'E - periscope sighted object which appeared to be a small sailboat.

1300: Closed object with 20mm. guns manned and 4" gun crew standing by in the conning tower. Determined object to be partly sunk and abandoned sampan of about 10 tons. Closed to 500 yards and fired 180 rounds of 20mm. and 60 rounds of 45 cal. (Thompson Sub Machine Gun) for indoctrination and training purposes. Backed clear, made another run and fired 5 rounds of 4"-50 cal. for same purpose. Results:~ One bird of Nipponese leanings definitely sunk; six more thoroughly scared; sampan now draws about two feet more water; 4" gun crew abashed because sampan was not blown out of the water.
