December 7, 1941 2030 Manilla Time aboard S-39
“LT, I see something off the port bow, real low and fuzzy”
“Give me direction and get plotting started on this contact, McMahon”
“330, range unknown, close to the horizon, call it 6,000 yards”
“Sonar, have anything there?”
“Nothing sir”
“Let’s go to battle stations, surface”
The crew of the submarine scurried rapidly as they got out of their bunks. Lt. Jorgenson threw on his pants and made it to the conning tower in under three minutes as he had to wait a moment while two men brought up the ready shells for the 4 inch gun.
“Situation #1?”
“Unknown contact, 6,000 yards at 330, sonar has nothing”
“Very good, make speed 10 knots and come to and let’s get a good identification on the contact before we call it in. Comms, get a message ready but do not send until I release the message.”
The old submarine started to increase speed and her ungainly bow pierced the waves for the next twenty minutes until the unknown contact was identified as a friendly Filipino fishing boat that had been seconded to the Army coastal patrol forces. She was acting as a sentinel and tripwire for the Lingayen Gulf defenses.
S39 motored away and continued to charge her batteries.
