Legionary government broke apart in early 1941, when the Iron Guard's Bucharest Rebellion caused Antonescu to reclaim all power, and later to join Romania into the Nazi German-led invasion of the Soviet Union. Perpessicius was isolated from political events. In 1942, with Cioculescu, Constantinescu, Streinu, and Vianu, he contributed essays dedicated to their mentor Lovinescu, celebrating his 60th birthday. They were collected in a single volume, published by Editura Vremea the following year—months before Lovinescu's death. In 1943, he published a second volume of Eminescu's "Opere", which included the alternative versions of lyrical works, including the "Luceafărul" poem. In 1944, he followed up with the essay volume "Jurnal de lector" ("A Reader's Diary"), which also included "Eminesciana", a collection of his "Revista Fundațiilor Regale" articles on the 19th-century poet. Also that year, he completed a third volume of Eminescu's "Opere", comprising anthumous variants of poems, from "Doina" to "Kamadeva".
