On October 10, 1945, Nahum Sarig and Yitzhak Rabin led the 1st Company of the Palmach פלמ"ח in a military operation, breaking into the Atlit Detention Camp מחנה המעצר בעתלית, and freeing the 208 detainees.
Sara Yoheved Rigler cites: "At 1 AM on the night of October 9, 1945, two platoons of the Palmach (the elite strike force of the Hagana), led by Nachum Sarig, cut the barbed wire fences on the north end of the camp. Some Palmach fighters stealthily climbed the watch towers and knocked out, tied, and gagged the guards. Others woke up the sleeping prisoners, whose belongings were already packed."
Zehava Yariv cites 210-220 Maapilim at Atlit Detention Camp מחנה המעצר בעתלית, who, according to rumor, were not going to be given certificates, and would be sent somewhere outside Palestine.
Yitzhak Rabin planned the raid, Nachum Sarig commanded the operation, and Yoske Yariv was among the leaders of the operation.
The main group of Palmach פלמ"ח went from Yagur קיבוץ יגור to Beit Oren קיבוץ בית אורן, then down the Carmel to Atlit Detention Camp מחנה המעצר בעתלית, where several men had already prepared the Maapilim, and would overpower the guards on watch.
Yitzhak Rabin and Nachum Sarig went with the Maapilim to Yagur קיבוץ יגור, while Yoske Yariv and the rest of the platoon stayed to clean up.
This signaled the beginning of the armed struggle of the Palmach פלמ"ח against the British, which contined until the summer of 1947.
In response, the British began deportion of Maapilim to internment camps in Cyprus Κύπρος, that operated from 1946 through the establishment of the State of Israel ישראל, in 1948.

On October 10, 1945, Joseph Bauminger was one of the 208 detainees freed from he Atlit Detention Camp מחנה המעצר בעתלית by the Palmach פלמ"ח.

Avraham 'Bren' Adan cites: “With all the tension and excitement that was in the air, I recall so distinctly the coolness with which Yoske gave his orders. As it turns out, whenever I recall the “Atlit Operation”, I recall that it was Yoske, the first Palmachnik who shot at a soldier of the British Army, and who coolly led his squad from spearhead position in attack, to cleanup position at the conclusion of the mission.”
