Four German Jagdstaffeln are combined to form Jagdgeschwader 1 under the command of Baron Manfred von Richthofen. Von Richthofen's 'circus' brought together many of Germany's finest fighter pilots and forced the Allies to concentrate their best squadrons opposite whichever sector the Jagdgeschwader occupied.
Significant numbers of SE5, Sopwith Triplane, Bristol Fighter and Spad S 13 enable Allies to regain air superiority.

2 June 1917
 

Western Front
French Army Mutinies: New French C-in-C Petain’s CoS Debeney informs Haig that, due to mutinies, French Army can give only minimal support in planned Allied offensive.
Haig decides to attack a key sector immediately and so distract Germans from French; Messines offensive already scheduled for June 7 fits the bill.
Western Front: Victoria Cross is awarded to Captain W.A. 'Billy' Bishop of No.60 Squadron, a Canadian serving in the Royal Flying Corps, for his one-man raid on Estourmel airfield near Cambrai in France in a Nieuport (B1566). Canadian ace Captain Bishop flies dawn raid on German airfield near Cambrai, and claims to have destroyed 3 Albatros fighters that rise to engage; returns to base in bullet-riddled Nieuport figher (Victoria Cross award on August 11).
Ed Note: there is a lot of controversy surrounding this mission. Since he flew it as a solo mission, (although he did seek a wingman for it), there are those that claim he made the whole incident up. A careful search of German records seems to indicate that there was no such raid on any German Jäger (fighter) unit on this date. However, Bishop did return with his plane shot full of holes, so something happened.
In his account, he states that the airfield he originally selected was completely socked in by overcast & fog: so he was forced to an alternative target. It is likely that the alternate target was either a two-seater unit’s airfield, or that of a temporary airfield of a ferry unit replacing single-seater fighters, and that otherwise, Bishop’s claim of being able to destroy three German aircraft while they were taking-off is accurate. Examination of German records for the Artillerie- and Aufklärungs- (artillery-spotting and reconnaissance) units, and Jagdstaffel 20’s (the ferry unit) in the area does support claims of German losses for this date.

In fact, he was not. Couple of biographies state:
In June, 1917, Göring was still flying with Jagdstaffel 27 (as commanding officer). Göring didn't command JG 1 until July 1918, becoming that until's last commanding officer.

Thanks, I was just curious! Couldn't remember if he was one of the early group of pilots to be selected for Jagdgeschwader1 or later.

3 June 1917
 

Western Front
French Army Mutinies: The government suppressed the news so as not to alert the Germans, nor depress homefront morale. The extent and intensity of the mutinies were disclosed for the first time in 1967 by Guy Pedroncini in his volume Les Mutineries de 1917. His project had been made possible by the opening of most of the relevant military archives 50 years after the events, a delay in conformity with French War Ministry procedure. However, there are still undisclosed archives on the mutinies, which are believed to contain documents mostly of a political nature; those archives will not be opened to researchers until 100 years after the mutinies, in 2017.

After the detonation, 9 divisions of British Second Army (Plumer) attack on 9-mile front and capture Messines-Wylschaete ridge.

8 June 1917
 

Western Front
French Army Mutinies: The repressions begin with mass arrests, which were followed by mass trials. Those arrested were selected by their own officers and NCOs, with the implicit consent of the rank and file. Unrelatedly, activists in some Russian units in France had been spreading word of the revolution underway in Russia and encouraging other Russians and Frenchmen to join them. The rebellious First Russian Brigade was encircled by loyal Russian troops in September 1917 at Camp de La Courtine and bombarded with cannon, killing 8 men and wounding 28. This episode became the basis of widespread false rumors that the French had bombarded French units earlier. Ferdinand Foch meets British CIGS William Robertson at Abbeville. Petain given right to order immediate executions, only orders 7 until July 13.

9 June 1917
 

Western Front
French Army Mutinies: Along with the deterrent of military justice, General Pétain offered two incentives: more regular and longer leave and an end to grand offensives "until the arrival of tanks and Americans on the front". For example, Pétain only launched limited attacks with massed artillery against German strongholds, like Fort La Malmaison. These were taken with minimal French casualties. The relative lack of rigor in repressing the mutinies provoked adverse reactions among some of the French Army's divisional commanders. General Pétain and French President Raymond Poincaré, on the other hand, wisely made it their policy to mend the French Army's morale and not act in a manner that could aggravate the problem of the army's motivation.
Britain: Julian Byng replaces Edmund Allenby as GOC BEF Third Army. Canadian Lieutenant-General Sir Arthur Currie becomes GOC Canadian Corps for duration of war.
