Cancelling the Mistral

In a piece of big news about Ukraine yesterday, the French government announced that it was halting the completion of the sale of two Mistral warships to Russia. The first such ship, the Sevastopol (yes, named after said city in Crimea), was due to be delivered in just over a month’s time. The two ships (the other named Vladivostok) would have given Russia the ability to launch amphibious invasions. The reason why this action was not taken earlier? Jobs. The construction of the two ships in French shipyards are a boon to the French economy. But after the recent “incursion” of Russian troops into Donetsk and Luhansk, Paris ultimately reconsidered the deal.

The Wall Street journal provides the graphic illustrating just how potent one of the ships would be.

Comet Siding Spring

Today we head off to the stars. Well, more appropriately the comets. The New York Times had a piece a little while back that looked at the orbits of several comets that pass near the Sun. Siding Spring in particular is highlighted because of its near approach later this autumn.

Borehole Graphics

Long articles often mean lots of vertical space. But it is only every so often when an item can complement itself with a narrow, vertical graphic. The Los Angeles Times has just that in today’s piece, looking at the layers of sedimentation from a borehole.

The Siege of Sinjar

For those of you unaware, the United States became involved yet again in Iraq. This time, air dropping humanitarian supplies to Yazidi refugees near Mount Sinjar in northern Iraq. (Also, we have started bombing ISIS positions near Irbil, a large city in Kurdish-controlled Iraq.) In today’s post we have the Washington Post and its look at just what is going on around Sinjar.

The Silk Road, Respun

Today’s piece comes from the South China Morning Post. It looks at the Chinese government’s efforts to connect China to trade partners via a maritime route. This is conjunction with efforts to build a railway intended to connect Europe and China via Russia.

Casualties in Palestine and Israel

Yesterday I mentioned the cost of the conflict in and around Gaza and we looked at a map of damage. Today, we look at a daily-updated graphic from the Washington Post that counts the human cost—the number of dead.

What Else Has Been Shot Down in Ukraine

The Boeing 777 jetliner was not the first nor even at this point the latest aircraft shot down over eastern Ukraine. Just yesterday, two Sukhoi Su-25 aircraft were shot down—the Ukrainian government claims from medium-altitude surface-to-air missiles fired from within Russia. While I was working on drawing something up to catalogue just what has been shot down, I stumbled upon this piece from the Washington Post that does just that.

The Air Defence Systems of Eastern Ukraine

Last week, separatists in eastern Ukraine shot down Malaysia Airlines Flight 17 with what appears to have been an SA-11 Gadfly missile. Separatists had previously claimed to have had this system in operation and days earlier shot down a high-altitude Ukrainian military aircraft—though not necessarily with the SA-11. How much more powerful is the SA-11 than the other two known surface-to-air missile systems the separatists have used to shoot down Ukrainian military helicopter and aircraft? Well, I decided to create a small graphic to show you that the SA-11 is a significant advancement over the shorter range systems in use up to now.

Cannon Along the Walls of Québec

In what I think is the last set of diagrams and illustrations describing the fortifications of Ville de Québec, we have the reason why the overall design and construction were so difficult as well as why there are so many star-like bastions pointing out of the walls.

The difficulty comes from the topography. Québec was, as I mentioned earlier, described by Charles Dickens as the Gibraltar of North America. It features a high, defensible cliff and then a city on the lowlands below it. But building a wall that defends it from the cliffs to the river is not easy. Especially because the angles and slopes of the walls have to account for the fact that enemy cannon near Cap Diamant could otherwise see very well into the city below. And therefore target the city. But how drastic was the descent?

And then to point the second, why so many stars? Well, the problem with straight walls is that if you manage to get beneath the firing range of the cannon along the wall, the defenders really cannot fire at you. And that gives you all the time to plant explosives and blow a massive hole in the fortifications. So the stars actually give the defenders nearly a complete field of fire along the entirety of the city walls.

Palisades and Ramparts de Québec

Today I have a little bit more about the fortifications near Artillery Park. The original fortifications were not massive stone works, because those take time. Instead, a lot of the original defences of the town were wooden palisades and earthworks. The following illustration shows the wooden defences of 1690.

The woodworks were more than just timber inserted into the ground. It involved some earthworks to support the wooden posts, but also to give the defenders a better view of the approaches. And a better firing position.

The palisades were divided into sections by redoubts. These were the strongpoints along the town walls.

But due to the ever-present fear of an amphibious invasion, the palisades were eventually replaced with an earthwork fortification. Trees were planted along the walls and they served as spikes to deter forces from scaling the walls.
