# John Karslake Karslake

John Karslake Karslake (died 21 June 1872) was a 19th-century Member of Parliament in the Canterbury region of New Zealand.

## Private life

Karslake arrived in Lyttelton on the Gananoque on 9 May 1860. The ship had sailed from London. In 1861, Karslake was living in the Cheviot district.
In about 1863, Karslake and Thomas Anson bought the Waireka run in the Malvern district. The business partners bought Run 210 in February 1868, and about 1870 the two bought the adjacent Run 277. The combined run became known as the Torlesse Station, named after nearby Mount Torlesse, inland from Springfield.
He was the brother or nephew of John Burgess Karslake.

## Member of Parliament

In the 1871 general election, Karslake and George Hart contested the Coleridge electorate. Both men had no prior political experience. Karslake and Hart received 35 and 27 votes, respectively. Karslake was thus returned. He resigned on 12 April 1872 to return to England.

## Death

Karslake died on the voyage home on 21 June 1872 by drowning.
# German submarine U-777

German submarine U-777 was a German Type VIIC U-boat built in World War II, launched on 25 March 1944, and commissioned on 9 May, by its sole commander, Oberleutnant zur See Günter Ruperti.

## Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-777 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-777 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
It underwent training with the 31st U-boat Flotilla, but did not participate in any patrols during its five-month career of active service. It was destroyed at 20:02 hours on the night of 15/16 October 1944, during a British air raid on Wilhelmshaven, Germany, at position 53°51′N 08°10′E﻿ / ﻿53.850°N 8.167°E﻿ / 53.850; 8.167. One crewman was killed.

## Other notes

* Despite the fact that many other U-boats lost men due to accident, disease and various other causes, the crew of U-777 did not suffer any casualties until she was destroyed and was sunk.
* The commander of the ship, Günter Ruperti, also commanded U-3039 during World War II, by which time he had been promoted to Kapitänleutnant. He commanded U-3039 from March 1945 until May 1945, taking up his post only about five months after U-777 was sunk.

The boat had a complement of between 44 — 52 men.

## Service history

U-776 participated in one war patrol that yielded no ships sunk or damaged.
On 16 May 1945, U-776 surrendered at Portland, UK. For a brief time she was designated N-65, a British N-class submarine, and toured the British coast and used for tests. She was later transferred to Loch Ryan, Scotland. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-776 was one of 116 selected to take part in Operation Deadlight. U-776 was towed out on 3 December 1945, but sank after foundering on the way to the designated area. She was one of 56 U-boats that sank before reaching the scuttling areas.
The wreck now lies at 55°08′N 05°30′W﻿ / ﻿55.133°N 5.500°W﻿ / 55.133; -5.500.
# German submarine U-792

German submarine U-792 was a Type XVIIA U-boat of Nazi Germany's Kriegsmarine during the Second World War. She was one of a small number of U-boats fitted with Hellmuth Walter's high test peroxide propulsion system, which offered a combination of air-independent propulsion and high submerged speeds. She spent the war as a trials vessel and was scuttled on 4 May 1945 in the Audorfer See, near Rendsburg.

## Construction

The U-792 was laid down on 1 December 1942 at the Blohm & Voss shipyard in Hamburg, Germany. She was launched on 28 September 1943 and commissioned on 16 November 1943 under the command of Oberleutnant zur See Horst Heitz.
When she was completed, the submarine was 39.05 metres (128 ft 1 in) long overall, with a beam of 4.50 metres (14 ft 9 in) and a draught of 4.30 metres (14 ft 1 in). She was assessed at 309 t (304 long tons) submerged. The submarine was powered by one Deutz SAA SM517 supercharged 8-cylinder four-stroke diesel engine producing a total of 210 metric horsepower (150 kW; 210 shp) for use while surfaced and two Walter gas turbines producing a total of 5,000 metric horsepower (3,700 kW; 4,900 shp) for use while submerged. She had one shaft and one 1.23 m (4 ft) propeller. The submarine had a maximum surface speed of 9 knots (17 km/h; 10 mph) and a maximum submerged speed of 25 knots (46 km/h; 29 mph) when submerged, the U-boat could operate for 127 nautical miles (235 km; 146 mi) at 20 knots (37 km/h; 23 mph) and when surfaced, she could travel 1.840 nautical miles (3.408 km; 2.117 mi) at 9 knots (17 km/h; 10 mph).
The submarine was fitted with two 53.3 cm (21 in) torpedo tubes (All fitted at the bow) and four torpedoes. The boat had a complement of 12 men.

## Service History And End

U-792 did not undertake any combat patrols and was instead assigned as a trials boat at first to the 5th U-boat Flotilla, followed by the 8th U-boat Flotilla, before returning to the 5th flotilla for the rest of the war and was used in March 1945 as a floating fuel bunker. In December 1944, her commander was replaced by Oberleutnant zur See Hans Diederich Duis.
The U-792 was scuttled on 4 May 1945 at 01:30 in the Audorfer See (Kaiser Wilhelm Canal), near Rendsburg during Operation Regenbogen.

## Wreck

The wreck of U-792 lay at 54°19′N 09°43′E﻿ / ﻿54.317°N 9.717°E﻿ / 54.317; 9.717 until 26 May 1945, when she was lifted by the British and taken to the Howaldtswerke in Kiel to be examined. She was first raised as a British prize and used for trials, but was soon torn down for parts and finally scrapped.

# John Law (comics)

John Law is a fictional character created by writer-artist Will Eisner in 1948. Law is an eyepatched, pipe smoking Crossroads Police Department detective, who, with his shoeshine boy sidekick Nubbin, was featured in an adventure planned for a new comic book series, but never published. The backup story was drawn by André LeBlanc. These completed stories were eventually adapted into Spirit stories, with John Law's eyepatch being changed to The Spirit's mask and Nubbin being redrawn to be Willum Waif, a Spirit supporting cast character.
The unpublished John Law story and the André LeBlanc backup were discovered by Catherine Yronwode among Eisner's original art files, and first saw print in 1983 from Eclipse Comics, under her editorship. They were next published in Will Eisner's John Law: Dead Man Walking (2004, IDW), a collection of stories that also features new adventures by writer/artist Gary Chaloner starring John Law, Nubbin, and many other Eisner-associated characters, including Lady Luck, created by Nick Cardy and Klaus Nordling, and Bob Powell's Mr. Mystic.

# Daniel Lessmann

Daniel Lessmann (January 18, 1794 in Soldin, Neumark – Sept. 2, 1831 between Kropstadt and Wittenberg) was a German historian and poet.
Born to Jewish parents, he attended Joachimsthalsches Gymnasium and went on to study medicine in Berlin. His studies were put on hold in 1813 when he joined the Volunteers Against Napoleon. He was wounded at the Battle of Lutzen (May 2, 1813), recovered, and remained in service until the end of the war.
After the war, he continued his medical studies and became a private tutor in Vienna in 1820, then in Verona in 1823. In 1824, he settled in Berlin to devote himself to freelance writing and contributed to the more important literary journals of the Restoration period. He also converted to Christianity during the same period. His work consisted of historical essays, short stories, poetry, and scenes of life in the southern countries he had visited. A collection of poems was published in Berlin in 1824 under the title, "Amathusia".
His literary work was influenced by Heinrich Heine, whom he became acquainted with and whose letters to Moses Moser frequently mention the aspiring writer. Lessmann took part in various literary circles and was a witty storyteller. His prose work includes "Louise von Halling," 1827, which was read by Goethe, and "Die Heidemuhle," published several years after his death. His translations of "The Nun of Monza" by Gioachino Rossini and "The Betrothed" by Alessandro Manzoni were major contributions to the introduction of modern Italian literature to Germany. He also wrote several volumes of history, some of which are only found in manuscript form.
In the seven years of his publishing career (1824–1830) Lessmann became deeply depressed as his aspirations of becoming a great literary figure were dulled by a disappointed public. In 1824, Lessmann converted to Christianity. According to a letter from Moser to Heine, Lessmann converted so that he might realize his hopes of literary success. The conversion did nothing to boost his literary career and his situation seemed hopeless. In 1831, on a walk from Berlin to Leipzig and Dresden with a new manuscript, trying to find a publisher, Lessmann hanged himself.

# Exercise Kangaroo

Exercise Kangaroo was a joint warfare exercise that was held by the Australian Defence Force in the 1970s and 1980s.
The first iteration of Exercise Kangaroo took place in 1974. The military units involved included the aircraft carrier HMAS Melbourne (R21), which took part in the exercise in the Coral Sea, before returning to Sydney. In October 1976, Melbourne participated in Exercise Kangaroo II, before sailing to her namesake city for the carrier's 21st birthday celebrations, then returning to Sydney on 5 November.
The 1989 iteration of Exercise Kangaroo was the largest military exercise to have been undertaken in Australia during peacetime up to that time. It involved 28,000 Australian and American military personnel. The exercise next took place in 1992, with over 12,000 Australian and American personnel taking part.
When Lieutenant General John Sanderson became Commander Joint Forces Australia (CJFA) in the early 1990s, his main task was to plan the Kangaroo series of exercises. Sanderson said that when the Vice Chief of Defence Force acted as CJFA in Ex Kangaroo 1989 he could not exercise command properly because he did not have a suitable command support system. Exercises Kangaroo 89 and '92 showed the need for the co-location of the joint headquarters. At one stage of Kangaroo '92 in the space of 30 minutes, two ships, one with a battalion of infantry embarked, were 'sunk' for lack of air cover.
