Excerpts from Chapter 5, "Gus Goes to War"
'Home from the sea'
'Bos'n Gus'
by Paul and Edith Lyman-Shafiroff
“It was quiet; all we could hear was the hum of our engines and the gentle break of the water when all of a sudden
the silence was broken by a call down from the crows
nest ‘Torpedo off the starboard!
Just below the waterline our ship shuddered and then the sound like broken glass was deafening."

"There was an explosion just forward of the engine room. * 4
Suddenly one of the crew yelled, ‘U-boat.’ We scanned the surface.
It looked like a huge whale coming up and then I could make out crew scurrying out of the coning tower."

U - Boat surfacing * 5
“I could see the Captain in the coning tower, his cap brilliant white reflecting in the sunlight as he surveyed the situation.
I was
treading water and very close to the submarine and for a brief moment we met,
eyeball to eyeball.”
“He just looked around, sized up the situation and saw no need to use his deck gun.
Our
ship was sinking fast. As silently as the U-boat appeared, she slipped back into
the sea leaving us to make out for ourselves.”

U-Boat evaluating the kill * 6
"Finally, a destroyer found us, hoisted us out of the water and later transferred us to another freighter."

Crew disembarking from Destroyer to freighter * 7
"Once onboard the freighter, a muster was taken of the crew; several wounded and one missing,
our captain… he had gone down with his ship."

HMS 'Leinster' U-100 fired one torpedo and missed, other torpedo tubes jammed
by debris and unable to fire again,* U -100 Ship's log entry

UB - 123 under the Command of Kpt.Robert Ramm & U-Boat 100 both engaged the RMS 'Leinster'.
Just before 10:00 a.m., while east of the Kish Bank, passengers aboard the "Leinster' saw a torpedo approach from the port side. It missed the ship,
passing in front of the bow. This was the torpedo U -100 fired and was unable to fire due to debris jammed in tubes.
UB-123 then, fired two torpedoes which quickly sank the vessel.
The RMS 'Leinster' carried 77 crewmembers and 694 passengers which included postal workers and app. 500 military personnel
Records indicate that 501 passengers perished.
UB-123 approximately one week later while on it's return to Germany, hit a mine.
The bodies of Oberleutnant zur See Robert Ramm and his crew of two officers and thirty three men were never recovered.
REPORT
U.S Naval Forces operating in
European Water, Destroyer Flotillas, Torpedo Station.
Base Six.
12 October, 1918.
To: Officer in Charge:
From: J.D. Mason, Chief Special Mechanic, U.S.N.
Subject: Report of sinking of S.S. Leinster.
|
I
took passage, going on leave, on the S.S. Leinster leaving Kingstown,
Ireland, sailing about 9.00a.m.At about an hour out from Kingstown, I was
sitting on the starboard side aft when I heard one of the soldiers
shout: "A torpedo".
We hoisted out two boats on the portside, both of which were just
reaching the water with the regular crews in them when I saw the second
torpedo coming directly for the starboard side. The second torpedo and boiler explosion produced an enormous amount of wreckage which fell so thickly in clouds together with steam and debris, that it was difficult to see anything at all. |

After the war, Baron von Löe designed engineering parts and presented in 1934 a design
for hardening a new type of bearing.
An Improved Method for the Production of Bearings (10)
Abstract of GB436705 436,705. Making bearings. LOE, BARON VON, 5, Bugenhagenstrasse, Hamburg, Germany. Feb. 6, 1935, No. 3853. Convention date, Feb. 6, 1934. [Classes 83 (i), 83 (ii), and 83 (iv)] Casting composite articles.-A copper-coated bearing-shell, of iron which is not hardenable by chilling, is heated in borax to 1050-1085 C. and inserted in a mould which is then filled with molten copper-lead alloy and plunged into cold water. The copper coating may be 1À5-2À5 mm. thick and the iron may contain 0À3 per cent of carbon, 0À3 of silicon, and 0À6 of manganese. Two halves 10 of a shell with lugs 11 are welded at 9, leaving a gap between them and after heating &c. are placed in a conical cast-iron mould 1 with a radially grooved base 6 of graphite. Clamps 5 are then fitted over the lugs 11 and others 4 on the mould. The bearing metal may comprise copper with 20 to 40 per cent of lead, deoxidized with phosphor copper and is poured until one half overflows at 8. Perforating by forging.-After boring, a hard ball, i.e. of chrome-nickel-steel is forced through a number of times to compress the metal.
