French Air Service WWI, Royal Air Force WWI-present, Royal Canadian Air Force 1946-67, 1967-present

Roundels are identifying insignias, usually in military use, meant for easy identification of vehicles and aircraft.  Roundel is a heraldic term: circle.  The French Air Force was the first to use this identification system in WWI: the tricolour in a 1:2:3 proportion.  The Royal Flying Corps followed, with the colours reversed.  All the Commonwealth air forces used the RAF roundel until 1946 when they were redesigned for specific countries.  
The RCAF roundel from 1946-1967 used a winsome maple leaf; after that, it became the maple leaf of the flag.

Australia, New Zealand, Rhodesia, South Africa 1927-46, 1947-57The Royal Australian Air Force put a red kangaroo in the centre of its roundel; the RNZAF a kiwi.  After 1946 Rhodesia put three spears over the centre of the RAF roundel; the South African Air Force, from 1927-1947, an orange centre, from 1947-57 an orange springbok. Now the South African roundel is very complicated: an eagle over a scalloped fort shape.

The original striped roundels were clearly for wartime identification when recognition must be instant and if the markings are indistinct, lethal. Also, the Allies were all pulling together under the RAF, thus they mostly used the RAF insignia.  WW2 was the last gasp of the British Empire, after it came the waves of decolonisation, 'empire' became an unuseable term, replaced by the more anodyne Commonwealth which today is almost without meaning — even the beautiful 1962 Commonwealth Institute building in London (listed Grade II) is now occupied by the Design Museum.  Commonwealth declarations of national identity within the dark blue border of the old British empire were a slow transition to contemporary warfare where, for example, the Canadian Forces operate under NATO command, whose roundel seems, graphically speaking, very ambiguous.

The RAF uniform was designed in 1920: capacious pockets, belted, long, deep vents, well-proportioned: it made everyone look tall. The service dress, above, remained unchanged until the 1960s.  All the Commonwealth air forces: the RCAF, RAAF, RNZAF, RSAAF had the same uniforms, nice smooth dark grey-blue worsted, unlike the scratchy army, evidently. The caps were quite amazing: they unfold to make a balaclava of sorts.

RCAF tartanThe RCAF tartan was invented in 1942, supposedly on PEI, probably at the Summerside base.  The CO of the base, nameless in the DND account, designed the tartan using red, blue and black pencils.  I like this very much: ordinary pencils were black graphite; red and blue leads, often in one pencil, were traditionally used in accounting, so the colours come from just general office equipment.  How very modest, to work within the limitations of one's desk.

Although one can buy the above muffler from something called Heritage Brands, the image on the DND website is more how I remember it — more like a pencil drawing:

3rd Canadian Division, 9th Canadian Infantry Brigade flashes, WWI. Player's Cigarette Cards, 2nd Series, No. 120.

These were the badges worn on sleeves and berets, painted on trucks and on signs identifying the units.  They had to be readable at a distance and when found on a body lying in the mud in a trench, so they couldn't be too fussy.  The Division patches of the Canadian Expeditionary Force followed a simple ordering system: the square colour block indicates the division, the brigade is the colour above it, the shape above it indicates the battalion.

All very tidy in the diagrams, what they looked like on the uniforms is somewhat more makeshift.

This Tschumi drawing of Alesia looks like a Roman bracelet flung onto the ground a long time ago, grass and weeds growing through it.  There is something about this project that keeps raising these images of decorative precious adornments.

Bracelets, Roman Britain, buried in the 5th century AD, now in the British Museum. 
Found at Hoxne, Suffolk in 1992. Alongside approximately 15,000 coins were many other precious objects, buried for safety at a time when Britain was passing out of Roman control.

Oxbow, Saskatchewan.

The classic prairie town: CPR tracks, Railway Avenue, Main Street crossing at right angles to it, the old town neatly conscribed by the section lines, the new town spilling north into the adjacent quarter-sections.  
Oil is near, developed in the mid-1950s, there is still a grain elevator, dating from the early 1900s, the oxbow is on the Souris River, population 1200, Highway 18 from the Manitoba border to Estevan follows the CPR line and becomes Railway Avenue as it divides the town from the elevator and its outbuildings.

There used to be one of these towns every 6 miles, or every township.  Now when you drive through southern Saskatchewan often all one sees is a roadside plaque saying that there had, once, been a town there.

We are such a long way from Monday and the Battle of Alesia.

In St Boniface, above, one can see the remains of an oxbow from the Red River. Detached from the main flow, it would have become, as indicated in this 1882 map, a slough perhaps flooding each spring.  Not to worry, the street grid has been drawn over it anyway, good flat land for development.  Just to the west (the map has west at the top) of the oxbow one can see the old seigneurial land divisions: thin narrow lots fronting on the river.
In the google satellite view, below, the edge of the oxbow is Enfield Crescent, the eccentric in the grid.  The seigneurial pattern is gone, but the road that skirted the swamp (also long gone) remains, permanently embedded in the street layout.

The greek key pattern is sometimes called the meander, after the Maeander River, now called the Büyük Menderes River that flows from central Turkey to the Aegean.  It winds through the Maeandrian plain in the manner of most prairie rivers, cutting into soft banks and creating oxbows.

Bernard Tschumi's interpretive centre for the battle of Alesia, 52 BC, where Julius Caesar's army surrounded Vercingetorix's Gauls: the site, in Burgundy, has this building referencing Roman wood fortifications, and will eventually have a second stone building up a hill, referencing the besieged Gauls. 

The battle was actually a long freeze: Caesar's troops circled the base of the plateau with 18km of 4m high fortifications, blockading the garrison of 80,000 soldiers at the top.  Vercassivellaunus, Vercingetorix's cousin attacked the Roman fortifications with 60,000 men, but Caesar's forces held the line.  Aside from the delight in typing the wonderful names of the Gauls, it occurs to me that these were very large armies, in modern terms the size of the Canadian Forces in total.

Caesar's eventual victory marked the end of Celtic power in what is now the territory from France and Belgium to northern Italy.

The exterior screen of Tschumi's Alesia museum is wood, the shape and pattern bring to mind the Greek key meander tiara of Alice of Battenburg: there is something both victorious and celebratory about this circlet sitting on the Burgundian plains.  Its pattern puts the screen into motion, it dazzles.  

Tiara of Princess Alice of Battenburg, circa 1903, her marriage to Prince Andrew of Greece and Denmark.

From their fortress the Gauls could see the Roman encirclement, which would have been nothing as solid as this single-point museum, thus the museum roof has been turfed as a displaced ground plane to indicate the original view from the Gallic heights. 
The roof planted with trees and shrubs is also a reminder of helmets with leaves and branches stuck into a netted cover as camouflage: a military strategy as old as war and still in use.
