Footage that eliminates

one of the candidates,

recorded
just a few months ago.

The United States Coast Guard
was preparing

to remove oil still leaking
from a sunken

World War II-era tanker
80 miles northwest

of the Dry Tortugas.

Multibeam sonar scans
revealed the size and layout

of the wreck
were an exact match

for one of the missing ships,

the "Munger T. Ball."

The coast guard
held a ceremony honoring

the "Ball's" crew,
who gave their lives

in service on that vessel.

- So that clears up
the confusion.

It's definitely not
the "Munger T. Ball."

narrator: That leaves
only one option left,

the "Joseph M. Cudahy."

- So tell us about
the "Cudahy" ship.

narrator: Just after 4:00 a.m.
on the morning of May 5, 1942,

the "Joseph M. Cudahy,"
a 430-foot oil tanker,

heads toward
the Straits of Florida

to refuel Allied ships

when they spot danger
on the horizon:

the sinking "Munger T. Ball."

Unarmed and unescorted,
they turn and attempt to flee,

taking evasive measures
to avoid the same fate.

A torpedo blows a large hole
in the starboard side.

- We were unprepared
for the U-boat threat.

And they took
advantage of that.

Riddled with bullets,

her oil tanks an inferno,
