While stationed in Piatra Neamț during the interwar, Coroamă took up various political and cultural activities, overseeing the Romanian Scouts and setting up a Military Club.

[2] Dumitru was the eighth of ten children born to the couple;[1] his more distant relatives included Eustochia Ciucanu, who was Staritsa at Agapia Monastery from 1960 to her death in 1992.

[7] He was again called to action during the campaign of World War I, overseeing defensive maneuvers on the fortified lines of the Trotuș, Oituz, and Uz river valleys.

[4] He earned distinction following the Battle of Mărășești: he was cited on October 11, 1916, for his "initiative and energy in holding on to a difficult position", and, on December 27, was made a Knight of the Order of the Star of Romania.

[7][5] In June of that year, he was included on a panel which proposed to transform Gorunzel meadow into the Satu Mare Airfield; the project was finally completed in September 1937.

[20] In November 1936, Coroamă presented military honors to Carol and Crown Prince Michael, who passed through Satu Mare on their way back from a state visit in Czechoslovakia.

[21] Alongside Greek Catholic Bishop Alexandru Rusu, he presided over the Satu Mare chapter of the Anti-Revisionist League, which campaigned against Hungarian irredentism.

[17] Coroamă rose to prominence after the events of autumn 1940, when the Second Vienna Award, which lost Romania rule over Northern Transylvania, engendered a political crisis.

As historian Ilarion Țiu notes, these "terrorist cells" were formed "from the second half of August, but on 3 September each member barely managed to have a revolver and the available hand grenades were very few".

In early September, as a sign of his cooperation with Sima, Antonescu appointed Coroamă to the post of General Officer in charge of Bucharest's Military Command, replacing the loyalist Gheorghe Argeșanu.

[4][32] When interrogated by Avram Bunaciu in early 1946, Antonescu himself recalled being poorly impressed by Coroamă's inaction, since it jeopardized Carol's personal safety.

"[33] An account originating with the Guardist Ilie-Vlad Sturdza has it that "the two generals said they could not order to shoot at the population as long as no bullets [had been] fired for the lost territories.

[29] An anecdote relayed by the old-regime politician Constantin Argetoianu presents another version of events, claiming that Antonescu had asked Coroamă to storm the area outside the Palace, though "without firing a shot."

[37] This scenario was upheld by the Guardist poet Radu Gyr: on January 22, he addressed "several hundreds" of his comrades, informing them that the Coroamă–Dragalina march was both welcomed and imminent.

[38] However, Coroamă had again resumed his mitigating position and, alongside other Iași Guardists, including Ilie-Vlad Sturdza, he fought to pacify the city and minimize bloodshed.

[39] Coroamă also sought an understanding with the Guardist leader, Gheorghe Grijincu, asking him to return control over government buildings, and also to pledge resistance in case of a Soviet attack.

[40] Another army leader, Constantin Sănătescu, noted that despite his standing as a "Guard sympathizer" Coroamă "behaved well, managing to peacefully quell the rebellion".

Coroamă openly praised Major Gheorghe Răscănescu and his soldiers, all of whom were Neamț-based, for their success in breaking out through the Soviet lines; he and other veterans congratulated Antonescu personally, who replied to thank them.

When Romania formally joined the Allied Powers, Coroamă was an alleged double-dealer, resuming his contacts with Sima, who now headed a pro-Nazi government in exile.

During Operation Spring Awakening in March 1945, generals Coroamă, Dragalina, Sănătescu, Petre Dumitrescu, and Radu Korne were reportedly involved in a Nazi-organized plot to overthrow the Soviet occupation forces.

[44] Gavrilă Ogoranu also recalled that in autumn 1947 Coroamă, who was based in Sibiu, traveled to Sâmbăta de Sus Monastery and met Arsenie Boca, with whom he planned various anti-communist activities.

[4] He was being subjected to repeated interrogations at Suceava penitentiary, where he was confronted with hostile witnesses Nicolae Popa and Lucian Pascaru; however, the Securitate only formally registered him as a prisoner on January 23, 1951, when the accusation was formulated as: "has supported the Iron Guard.

[4] In his samizdat memoirs, Pandrea would include an account of "Carol II's odyssey, with its exact details", claiming that it was partly sourced from "things confessed to me by Mihail Manoilescu and General Coroamă".

"[48] Reports also suggest that he was fed broths made of beechnut and hay, a starvation treatment which pushed him to gnaw on his straw mat, or on wild dandelions.
