The submarine F-14 sinks, last week, off the Adriatic harbor of Pola, after being accidentally rammed by the destroyer Giuseppe Missori.

Sea: Rough. Weather: Stormy. Depth: About 140 ft Position of submarine: Almost vertical, making easy the attachment of hoisting chains.

Located within one hour, by aviators peering from seaplanes.

Salvage Director arrives within 95 minutes after the disaster, by airplane, from Rome. Name: General Naval Engineer Bernardis, subordinate to Admiral Foschini.

Communication: Established at once by submarine telegraph.

Air Hose: Attached within 24 hours to breather fittings integral with hull.

Asphyxiation: Rapid, because vertical position of submarine caused acid to spill from storage batteries and to come into contact with the salt water, generating deadly gas impossible to counteract with fresh air from hose.

All Dead within 24 hours.

Submarine Raised in exactly 34 hours.

Weight: 318 tons, when submerged, requiring two giant pontoons to float.

The submarine S-4 sinks (TIME, Dec. 26), off the Atlantic harbor of Provincetown, after being accidentally rammed by the destroyer Paulding.

Sea: Rough. Weather: Stormy. Depth: 104 ft.

Position of submarine: Horizontal and half sunk in mud, making difficult the attachment of hoisting chains. Located within seven hours, by sailors

with dragnet apparatus. Salvage Director arrives within 24 hours after the disaster by train and airplane from Norfolk, Va. Name: Captain Ernest J. Kind, commanding officer of the U. S. S. Wright, subordinate to Rear Admiral Frank H. Brumby.

Communication: Established after one day by divers tapping on the hull.

Air Hose: Attached within four days to submarine's "ears" (S C tubes).

Asphyxiation: Slow, since little acid spilled due to horizontal position; but absence of air hose rendered slow asphyxiation sure.

All Dead within three days. Submarine Raised in exactly three

months. Weight: 1,092 tons, when submerged,

requiring six giant pontoons to float.
