Yeah, 'demonstrate' is one of those weasel words in a military context. It can be anything from a mere parade, to a full-scale attack.

For example, in an earlier post, the British naval forces "demonstrated" in an attempt to intimidate the government in Athens (it worked).

Here, the British "demonstrated" their military muscle: in the context of this sentence, it would have been in the context of a raid.

Not precisely 100 years ago today, but during the First World War, and ongoing for the several years of it. A bit of archaeology, the "White War": http://motherboard.vice.com/blog/gl...ampaign=posteng

Which in and of itself is fascinating, but also goes to show why there were 13 Battles of the Isonzo: that sector on the Austro-Hungarian/Italian front was practically the only path to cmoparatively military operations.

Battle of the Somme: Great (only “Great” compared to earlie disasterous British advances) British advance (third phase) on the Somme, a six-mile front to depth of 2 or 3,000 yards. Flers, Martinpuich, Courcelette and whole of High Wood taken.

Aeroplane co-operation with tanks instituted by the British Flying Corps:
During the Battle of Fleurs-Courcelette, No.7 and No.34 Squadrons, Royal Flying Corps, support the British Army's first tank attack.

Battle of the Somme: French attack, taking Vermandovillers and Berny, Deniecourt surrounded, German reserves much cut up, ‘many’ prisoners.

Jasta 2 (Full name: Jagdstaffel 2) has its combat debut. https://en.wikipedia.org/wiki/Jagdstaffel_2 and http://jasta2.org/history.php
After Max Immelmann's death, Kaiser Wilhelm II had ordered Oswald Boelcke grounded for a month to avoid losing him in combat soon after Zimmerman. He had become such an important hero to the German public, as well as such an authority on aerial warfare, that he could not be risked. Given a choice between a desk job and a tour of the Middle East, Boelcke downed a Nieuport over Douaumont on 27 June and reported to headquarters. Boelcke was detailed to share his expertise with the head of German military aviation. What had been known previously as the Deutsches Heer's Fliegertruppen des deutschen Kaiserreiches was being reorganized into the Luftstreitkräfte in mid-1916; this reorganization was inspired by Boelcke. At this time, Boelcke codified his Dicta. He also shared his views on creation of a fighter arm, and the organization of fighter squadrons.
Boelcke was sent on a tour of the Balkans. He transited Austria to visit Turkey. Upon his return swing, he visited Bulgaria and the Russian Front. Boelcke would be visiting Wilhelm in Kovel when he received a telegram from the head of German aviation, Feldflugchef (Aviation Chief of Staff) Oberstleutnant Hermann von der Lieth-Thomsen, appointing him to raise, organize and command Royal Prussian Jagdstaffel 2. Boelcke, by then a Hauptman, was given permission to choose his own pilots to form a fighter squadron. Among his first selections upon his return were Manfred von Richthofen, Erwin Böhme and Hans Reimann. The first aircraft arrived on 1 September; two Fokker DIIIs and an Albatros D.I. On 16 September, Boelcke's new squadron received five new Albatros D.Is for the pilots, and an improved Albatros D.II for the Staffelfuhrer. Boelcke promptly put the new planes in the air on the first-ever fighter unit effort to gain local air superiority. At 1300 hours 16 September, Boelcke and five of his pilots took off; they intercepted a British bombing raid on Marcoing Railway Station. While Boelcke held aside, his five wingmen bounced a British formation of 14 planes, broke it up, and shot down two; one of them an F.E. 2, by von Richthofen. The master himself added another. (Another source says 5 total British aircraft fell). That night, a German army tradition was ditched and a new German air force custom established when the enlisted men were invited into the Jasta's social center.
Captain Tom Rees becomes the first official confirmed kill of Manfred von Richthofen (the future Red Baron): http://imgur.com/q2N07Bn

Edit to add: A friend on another forum managed to track down details on yesterdays: Royal Flying Corps aircraft and balloon collide with fatal results. The details:
Lieutenant Clarence Edwards Nooth Cooper RFC 6 Kite Balloon Section - Died of accidental injuries 16 September 1916 aged 25, following balloon cable being struck by FE2b 6971 of 18 Squadron, kite balloon was cut adrift and his parachute failed to open, he fell to the ground near Montauban. LIEUTENANT C. E. N COOPER, Lincolnshire Regiment, attached R. F. C., who fell on September 16, in his 26th year, was the eldest son of Mr. and Mrs. Geo. C. Nooth Cooper, of South Norwood. He was educated at Whitgift Grammar School, Croydon, and after six years service in the Mercantile Marine, he obtained an appointment with Messrs. Geo. Cradock and Co., wire rope makers, of Wakefield, Yorks. He enlisted in the Queen Victoria Rifles in October, 1914, and obtained his commission in the Lincolnshire Regiment Special Reserve, in February, 1915. In April, 1915, he was sent to the front and served there with his regiment until about three months ago, when he was lent to the Royal Flying Corps as a balloon observation officer. His death was caused by his parachute failing to act when compelled by an accident to descend from his balloon.’

Seventh Battle of Isonzo: Italian offensive suspended due to bad weather after 17,000 casualties and 4,500 captured Austrian PoWs. Breaches in wire not wide enough for rapid infantry assault. Another source realistically reports: 7th Battle of the Isonzo comes to an end with the Italian offensive achieving little gains for heavy casualties.
Italian success (as defined how ?) on the Carso. (What is this Carso of which they speak? There’s a “Monte Carso” in what is now Trieste Province, Italy; but Trieste at the time, belonged to Austria-Hungary, and the Italians got nowhere near the mountain. I don’t know what this means, but it was reported by: http://www.firstworldwar.com/onthisday/1916_09_17.htm
