Rhino Barges

One of the dullest, coolest, more bizarre and fascinating pieces of kit used in Normandy.

Which NO ONE REALLY CARES ABOUT.

BUT I DO AND YOU SHOULD TOO.

#WW2 #SWW #History

 Planning for Overlord and Neptune had a serious snag, how to get troops from LSTs onto the beach as simply ramming them onto the beaches and dropping the ramp was known to damage the exceptionally vulnerable LSTs and felt to be unsustainable in the mid to long term. /2
LSTs were essential in sustaining Overlord's progress and were a subject of major headaches in the planning phase, and a real subject of friction when it came to launching additional amphibious operations such as Dragoon.

A single LSTs loss represented a capability nick. /3
So, logic dictated, we don't really want these remarkable but rare and highly valuable vessels constantly doing beach landings, we want something to act as a medium between ship to shore, and in came the (mostly) American designed Rhino. /4
I fucking love Rhinos.

Seriously.

Graceful lines of pure industrial pedigree.

Modular.

LOOK AT IT. /5
They were clearly POPULAR with troops disembarking from transport ships.

FULL OF GRACE.

MUCH LOVED.

THEY WERE TRUSTED.

SOLDIERS AND SAILORS HAD FAITH IN THEM.

*Undeniable goodest Rhino. /6
Jim Walton served in the Durham Light Infantry in their Carrier Platoon, landed in a Universal Carrier on D+4 off a Rhino barge.

"We were glad to get off the boats! It was a little bit rough. We landed on water but we didn't get wet as we were in a vehicle." /7
Rhinos were modular craft but many running from transport ships inland were pretty massive, say 180 ft (54m) long.

They also weighed an absolute ton when loaded, easily overtaxing the small 60 HP outboard engines. /8
Rhinos were utter pigs to handle at the best of times with a max speed of 3 knots & LCI were occasionally assigned to marshal them as mini-tugs.

Even these were far too weak to to work deal with such wallowing beasties when fully loaded which could easily come to 500 tons. /9
The Great Storm forced revision to the LST to rhino to beach plan, as many Rhinos suffered serious damage and performed poorly in rough weather.

This pushed the direct beaching of LSTs as closer to the norm, and reduced reliance on Rhino transfer. /10
The real trade off in adopting direct beaching of LSTs as the norm was the increased number of damaged ships, but the Admiralty came to approach of the move as it allowed much faster unloading - and LST repair turn around was much better than feared. /11
Rhino ferries continued in use in providing additional unloading capacity away from Mulberry B, also seeing use as pontoons. /12
There's an awful lot of stories of Rhino misadventures whilst unloading, where their lack of power led to some exceptionally hairy escapades, and flat out fiasco, but these were a remarkable leap forward. /13
Unsurprisingly, the idea soldiered on.

As a simple, modular system to build pontoons and ferries is undeniably useful.

So the next time you see one of these, raise a glass to Rhino.

AS CURRENTLY ALMOST NO ONE ELSE WILL BUT ME. /thread

So when it first appeared in Normandy, the Sherman Firefly and it's meaty 17 pounder represented an ideal combo of reliable chassis, great gun and devastating firepower right?

Ummm...

Truth is a bit more complex. /1
#WW2 #SWW #History


Deliveries of Firefly to units only commenced in April 1944,
just a few weeks before Overlord & left minimal time for familiarisation.

Armoured Regiments mostly utilised Fireflies on a basis of 1 per troop of 4 tanks. /2


Finally each armoured regiment troop had access to integral, meaty, anti-tank firepower capable of dealing serious damage to any German AFV likely to be encountered. /3


The dual purpose 75mm gun was quite capable of laying down a reasonable HE shell or AP round for dealing with Panzer III or IV.

Firefly's 17 Pounder had.... problems with HE, but excelled at tank killing. So Tigers and Panthers would need to be wary. /4


Firefly's design history dated back to March 1943 when the General Staff published "Policy on Tanks" which effectively stated the majority of tanks should have a good HE weapon and...

The Churchill Tank in Normandy: Part One 40-44

Ratty Relic or Bocage Buster?

How did it go from a hated, atrocious POS tank worthy only of the scrapheap to a reliable, trustworthy, survivable and popular gun tank in action?

Another pertinent tale. /1
#WW2 #SWW #History


At 38 tons the Churchill was clearly a beast but a manageable one, given concerns about railway loading gauge had informed development (even then you still had to remove the side air louvres for rail tpt).

As always, compromise & industrial limitations underpinned design. /2


Early Mk I and Mk II were respectively armed with a 2 Pounder with coaxial Besa in the turret but with differing hull armament, I - 3" howitzer, II - Besa machine gun.

88.9mm of front armour provided excellent protection for the five man crew, and WS No. 19 provided comms. /3


Other than being undergunned another problem was, they didn't work very well.

But why?

It call comes back to, you guessed it, June 1940 - at the height of that invasion-scare summer.

AFV cupboards were bare so the initial models were raced into production in June 1940... /4


there wasn't time for proper prototyping or accompanying development as the imperative to have ANY gun tank pushed Vauxhall to the limit in the race to get SOMETHING, ANYTHING into the field.

9 RTR probably enjoyed the dubious honour of the first Churchill deliveries. /5

So you're a company commander in Normandy, trying to coordinate your three platoons in action, & liase w supporting tanks & some arty, & keep battalion headquarters appraised, & adapt as needed.

You know your platoons' sets are a bit crap.

What do you do? /1
#WW2 #SWW #History


The whole thing is a bit of a juggling act.

The core set at Company HQ was the WS No. 18 set, linking in with WS No. 38 sets used by platoons & back to Battalion HQ.
0.25 Watts
6-9Mhz
2.5 miles range with R/T and 4 miles with W/T
Interference in woodlands/around armour /2


The 18 set was more durable than the WS No. 38, but much less powerful than the popular WS No. 19 and 22 sets... then again you can carry it about and not worry about a vehicle or cart for it in action. /3


Much like the WS No. 38 set, the No. 18 set also relies on a rather conspicuous aerial - 10' (3m) high.

The Army knew such height wasn't desirable and trials of ground trailing aerials for the 18 and 38 sets were underway in theatre but there were problems... /4


It performed poorly on wet ground, and Normandy was... frequently soggy, whilst movement through thick undergrowth could damage the copper wire which also had the habit of snapping if stepped on.

So signallers, and those around them, had to be pretty considerate in action. /5

So you're a platoon commander in Normandy, you've got your three infantry sections, and you need to quickly confer with your company commander. You're wireless op is ready with his WS No. 38.

Easy right?

Well... read on. /1
#WW2 #SWW #History


The WS No. 38 set was a compact wireless set (hence WS) assigned at the platoon level, allowing communication to headquarters, who used the bulkier and more powerful as WS No. 18.

A dedicated wireless operator controlled the set at platoon HQ, speaking via the throat mic. /2


WS No. 38 was usually controlled by Wireless Op's throat mic. Mounted on the chest with a nifty webbing cradle.

Aerial: three piece 12' aerial or 4' 'battle' aerial
Power: 0.2 Watts
Frequency: 7.4 - 9 MHz
Weight: 6kg
Battery: 20 - 35 hrs
Range:


You've probably noticed the set was under powered for the intended role, 0.2 Watts didn't really cut it.

The design also came under heavy criticism for unreliability as the key junction box and six point lead connector was known for a troubling propensity to break. /4


These were not pieces of kit used lightly, as you'd have to dodge, duck, dip, dive and... dodge, on a regular basis.

If the junction box broke, it rendered a serviceable set completely and utterly useless. /5

So how easy was it for British & Canadian soldiers to keep clean and healthy in Normandy?

Couldn't be too hard, right? /1
#WW2 #SWW #History


You're an front line infantryman in a two man covered slit trench. Maybe 100m from the enemy

From dawn to dusk you're hunched underground, making the best of things in a covered trench 6' long, 3' deep and 2 1/2' wide or so.

With your mate crammed in there with you. /2


You know you're under constant observation by enemy observers and marksmen, who scan the ground looking to punish any foolish or unlucky opportunity target.

They may not get you, but their rounds may well kill or maim your friends. /3


Night offers a modicum of respite.

In darkness fresh, hot grub is bought up in large thermos flasks from the cooks in B Echelon. It's good hearty stuff.

The problem is the closer you are to the enemy, the more likely it'll be delayed or obliterated by an errant 155mm shell. /4


You can always tuck into food from your compo crates, which is fine, or 24 hour ration pack... or the famed emergency ration in a sticky spot.

The latter is really nice.

Chocolate laced with amphetamine or high dose of caffeine.

Yum. /5

Today is Jayanti of Udham Singh, the man who assasinated General O Dwyer, responsible for the Jallianwala Bagh massacre and the atrocities that followed, a true hero.


His real name was Sher Singh, born on Dec 26, 1899, to a poor peasant family in Punjab’s Sangrur district. His father, Tehl Singh, worked as a railway gate keeper at a level crossing in the Uppali village of Punjab.

Having lost both his parents when he was small, he along with his brother Mukta Singh, grew up in the Central Khalsa Orphanage in Amritsar. Following the Sikh initiation rites, he got the name of Udham Singh.

In 1919, he left the orphanage after passing the matriculation exam. In that year Punjab was in turmoil, with massive protests breaking out against the British rule.

Around 1500 Indian civilians, in Amritsar, protesting against the deportation of nationalist leaders, Dr.Saifuddin Kitchlew and Satyapal Dang, were brutally massacred at Jallianwala Bagh in Amritsar. While Gen Dyer led the carnage, he was backed by the Lt. Governor O’Dwyer.

In 1937, a trucker got frustrated waiting for his cargo to be unloaded. He later sold his company for $1.1 billion.

Here’s the story of how Malcom McLean made a billion dollars and which startup could be following in his footsteps. (Inspired by our episode with @laurabehrenswu)


In the early 1950s, the shipping industry was a dying business.

New York’s docks were handling half as much domestic cargo in the early 1950s as they had been in the depressed 1930s.

In thirty years, no one had invested significant money in coastal shipping.

Why?

As McLean found out, loading ships was difficult and slow.

A truck or train would deliver items to the port. Each item was unloaded separately, recorded, and carried to storage.

When a ship was ready, each item was taken from storage, counted again, and hauled on-board.


The cost of this labor was significant. As one expert at the time explained:

“A four-thousand-mile voyage for a shipment might consume 50 percent of its costs in covering just the two ten-mile movements through two ports.”


Yet, despite the industry’s issues, it felt little pressure to change.

Foreigners were barred from operating domestically. Cartels ran international routes. And gov. subsidies eased the pain of labor costs.

Reshaping the industry needed an outsider.

Enter Malcolm McLean.

RANI TARABAI the nemesis of Aurangzeb

The forgotten warrior queen who didn't allow the tyrant to trample upon Hindu rule which was passing through its darkest phase. Courage and resilience. A falling empire, personal tragedies and a vicious enemy. None could shake her.

(Thread)


Tarabai, the Maratha queen (1675-1761), is perhaps one of the most important contributors to the breakup of the M0ghul empire. She prevented the Maratha rule from disintegrating when it was at its lowest with almost all forts in M0ghul hands.(1)

Aurangzeb’s dream of a pan India dominion was destroyed in the hills and forts of western Deccan.(2)

First she survived the M0ghul onslaught, later on carrying the battle into M0ghul territory, raiding and then creating permanent outposts. Had she buckled there may not have been Maratha hegemony in the 18th century, which reduced the M0ghul control to a small area.(3)


She was the daughter of Hambir Rao Mohite, Shivaji’s cmdr in chief, and got married to Shivaji’s younger son Rajaram. She was well trained in sword fighting, archery, cavalry, military strategy, diplomacy and other subjects of statecraft.(4)

Along with police, well-connected and well-intentioned people arrived at the Lindbergh estate. Military colonels offered their aid, although only one had law enforcement expertise—Herbert Norman Schwarzkopf, superintendent of the New Jersey State Police. The other colonels were


Henry Skillman Breckinridge, a Wall Street lawyer; and William J. Donovan, a hero of the First World War who would later head the Office of Strategic Services (OSS), the forerunner of the CIA. Lindbergh and these men speculated that the kidnapping was perpetrated by organized

crime figures. They thought that the letter was written by someone who spoke German as his native language. At this time, Charles Lindbergh used his influence to control the direction of the investigation.

The deepest banking crisis of the Great Depression was touched off by the pending failure of two Detroit banks in early 1933. For several weeks, by law, every bank in the entire state of Michigan was closed for business. It was from these beginnings that a national banking

crisis engulfed the final days of the Hoover Administration. What transpired to bring on such a calamitous event? How did individuals cope in that interval without a banking system?

PAKISTAN-INDIA WATER ISSUES – HOW INDIA STOPPED WATER IN PAKISTAN's CANALS IN 1948

Thread

After partition in 1947, the water system was also bifurcated between Pakistan n India.

India cheated Pakistan when on April 1, 1948, India suddenly n without warning stopped...
1/n


...the supply of waters flowing into Pakistan's Central Bari Doab and Dipalpur Canals.

The boundary award on the partition of the sub-continent had left the headworks of these canals in Indian territory, and in accepting it India had implied her willingness to leave...

2/n


...the historic distribution of common waters undisturbed.

India's action was therefore in flagrant disregard not only of international law n morality, but of her solemn commitments with Pakistan and a gross violation of this country's historical rights over common waters.

3/n

Faced with a threat of utter desolation of millions of acres of fertile land, Pakistan had perforce to sign a document with India in which she agreed to "India's progressively diminishing water supplies to these canals and to the West Punjab government's tapping...

4/n

...alternative resources".

A specific reservation was made in the document with regard to India's claim that she had full property rights over waters flowing into her territory, and could therefore use them as she liked.

The issue was, however, to be examined...

STORY OF PURANAS AND SUB PURANA (उप पुराण).

We have already gone through the series on importance & characteristics of all the eighteen Purans. We also know that originally there were hundred crore shlokas but were divided by Vyas in each Kalp and was compiled as eighteen Purans


for the common people to understand it properly and now their total is about four lakhs.

In Brahm Puran, Brahma preached this to Marichi. So this Puran of ten thousand shlokas is called Brahm Puran.

In Padma Puran, the base of the story is the appearance of Brahma on a lotus(Padm) from Vishnu' s navel.This has fifty five thousand shlokas.

Vishnu Puran is primarily based in Varah kalp. This book is on Vishnu and this book has twenty three thousand shlokas.

Vaayu Puran is written in Shwet Kalp and has twenty four thousand shlokas. Here Vayudev preaches about Dharma.

In Bhagwat Puran, which is written with the base of Gayatri mantra describes Dharma extensively. It has 18000 shlokas. It also mentions the story of Vritrasur.

In Narad Puran, which has twenty five thousand shlokas, is a sermon on Dharma by Narad based in Brihad Kalp.

Markandeya Puran has nine thousand shlokas and here it is through the birds that Dharma is described.

An interesting set of games that I've been vaguely interested in since I was a kid, after seeing one at a friend's house and never being able to find it again, was the BATTLES IN A DISTANT DESERT/BATTLES ON DISTANT PLANETS series.


These are turn-based wargames for windows 3.x, sharing the same engine.
Battles in a Distant Desert is from 1992, and is based on the first Iraq war (Desert Storm)


and Battles on Distant Planets is from 1991, and takes place in SPACE!
I'm pretty sure this is the one I played as a kid.


They've got 3 options to play with:
* Player vs. Player
* Player vs. Computer
* Computer vs. Computer

So it's a 0-2 player game!


They also did a DOS strategy game called "STARDATE 2140.2: GALACTIC CONQUEST" in 1990, but it seems to be lost.
All the games share an experimental AI system based on neural networks.
