Hawaii
  • East of Lahaina Roads, Hawaii, Japanese submarine I-19 prepared to launch her E9W1 "Slim" floatplane for a night reconnaissance over Pearl Harbor. The submarine is spotted and an American patrol vessel. After the launch of the floatplane, I-19 spent the next hour successfully evading the patrol vessel. Nearly 3 hours later, the floatplane returned and reported 1 carrier (USS Saratoga), 9 cruisers, and 6 smaller warships in Pearl Harbor. ww2dbase [Pearl Harbor Navy Base and Ford Island Naval Air Station | Oahu | CPC]
