After the location of the headquarters was betrayed in 1947, Kasperavičius and his colleague blew themselves up to avoid capture in the ensuing firefight.

Juozas Kasperavičius was born on 17 August 1912 in the village of Jokūbaičiai of Jurbarkas district to a family of well-off farmers.

When he was in the sixth grade at the Jurbarkas Gymnasium, he decorated the Girdžiai town church during summer vacation.

After completing his studies Kasperavičius, now ranked junior lieutenant, was assigned to serve in an artillery regiment.

[7][1][9][2][3][8][6]Kasperavičius was preparing for his final exam to become a captain, however, the plans were interrupted after the USSR occupied Lithuania in 1940.

Kasperavičius and thirteen other pilots spent more than half a year in German prison camps in Raseiniai, Prussia, and Austria.

[1][9] As the Soviet army was getting closer, Kasperavičius along with his wife and daughter returned to his home village in Jokūbaičiai.

[4] Juozas's wife, and her acquaintance, a storage worker of the hospital, informed the partisans of the injured pilot.

For example, having with him a fake passport in the name of Antanas Klimas, Kasperavičius often traveled all over Žemaitija on various partisan matters.

There, one NKVD agent immediately drew attention to his hands, which were white, not appealing to the appearance of a mason.

To the great surprise of the agents, the man confirmed after a few hours of conversation that the arrested person is indeed a mason, as he knows more about furnaces than he himself.

Kasperavičius met with the local leadership extensively to coordinate the establishment of a military disitrct and its domestic organization.

[7] Kasperavičius planned to relocate the headquarters after Easter but failed, as the location was betrayed much sooner, and MVD soldiers and agents began surrounding the old bunker.

They also attempted to burn important documents, but failed to significantly destroy them, and as such much of the district's newly formed leadership was discovered and eliminated.

[7] [1] The bodies of Kasperavičius and his colleague were buried in the yard of Šubertinė, the NKVD headquarters building in Tauragė (now a museum).
