[5] His son, Georgios Danglis (1809–1896), was born in exile in Corfu, entered the Hellenic Army in 1828 in time to fight in the last campaigns of the War of Independence, and after a long career rose to the rank of major general.

[8] After participating in the suppression of the failed Nafplion revolt against King Otto in early 1862, Danglis' father was promoted to major and the family moved to Agrinio.

From this small provincial town Danglis experienced the tumultuous events of Otto's ouster, the arrival of King George I in 1863, the union of the Ionian islands with Greece, and the outbreak of the Cretan Revolution of 1866–1869.

The artillery, recently enlarged due to a possible Greek participation in the ongoing Russo-Turkish War of 1877–78, was facing extreme shortages in qualified officers at the time.

[15] Popular enthusiasm ran high, especially after the Russian army overcame the stubborn Ottoman resistance at the Siege of Plevna—much admired by Danglis in his notes—and advanced towards Constantinople.

[16] Danglis served in the army of Eastern Greece, under the command of Major General Skarlatos Soutsos [el], a nominal force of 6,800 men—Danglis estimated the effectives at 5,500–6,000 at the most.

On the next day, however, the Greek government ordered its troops to return home, as the Russians and Ottomans had signed an armistice on 19 January, and the Great Powers had put pressure on Athens to endure peace.

[18] From Lamia he observed the failure of the uprisings in Thessaly and Epirus and Crete, while Greek interests were championed on the diplomatic front by Great Britain as a counter to Russian designs.

[22] The artillery was moved to Lefkada in October 1878,[23] and to a newly constructed but ephemeral encampment at Lepenous—not coincidentally, the electoral district of the then Minister of Military Affairs, Dimitrios Grivas—in May–July 1879.

[26] On 21 December, he published in the daily Athens newspaper Efimeris [el] an anonymous article—signed only as "Omega" and identifying himself only as a professional officer—requesting the removal of the army from the influence of politicians.

[26] The ongoing dispute over Epirus and Thessaly meant that the army had been maintained far larger than its peacetime establishment since 1878, to the detriment of the already feeble Greek budget.

His life and career for the next two years is unknown, as little material survives in his archives, apart from reports on tests of Krupp-type artillery packs for mules in April and August 1883.

[33] On his return was appointed adjutant to Brigadier Victor Vosseur, the head of the 1884–87 French military mission, which had been tasked by Trikoupis with modernizing the Greek Army.

[34] Nevertheless, the Deligiannis government was involved in a major diplomatic and military crisis with the Ottoman Empire, resulting from the de facto annexation of Eastern Rumelia to the Principality of Bulgaria in September 1885.

[35] Under the pen name "Shell" (Ὀβίς), Danglis published two articles outlining his opinion on the best deployment of the army in the Akropolis newspaper on 5 and 11 January.

The clashes lasted until a ceasefire on 11 May, and although generally the Greeks held their own and scored some successes, Danglis considered it fortunate that the ceasefire took place when it did, as Greece had about 40,000 men deployed facing three times as many Ottoman troops; without any readily available reserves, and exhausted after three days of fighting, the Greek front was brittle, and any Turkish breakthrough would face no opposition to advancing to Larissa.

[38] Furthermore, in two places Greek troops had performed poorly: at Koutra, 300 men of the 5th Evzone Battalion had surrendered to the Turks, while at Patsos an entire infantry company fled after an attack by a much smaller Turkish detachment.

[42] As a member of the Athens garrison, Danglis took part in the festivities to celebrate the coming of age of the Crown Prince, the future Constantine I, in December.

Operations had largely concluded so that his main task was completing the occupation of Northern Epirus, pacifying the local population, and strengthening Greek claims in the region, which were being challenged by Italy.

As a result, on 29 August Danglis—promoted to Lieutenant General at about that time[52]—was ordered to interrupt his vacation and participate, as the official representative of Greece, in the French great field manoeuvres of the year, that had already begun.

His participation there, his reputation as a "true friend of France", as well as a judicious and carefully worded interview in the Le Temps that paid tribute to the contributions of the French military mission, quickly calmed the situation and helped restore the Franco-Greek relationship.

[53] In late 1914, he left the army and went into politics, joining the Liberal Party of Eleftherios Venizelos in 1915 and elected as an MP for Epirus representing Ioannina.

Danglis was appointed nominal commander-in-chief of the Greek Army, a position he retained until near the war's end when he returned to his parliamentary office.
