Hilda הילדה Orion took on passengers from Bratislava, who had come down the Danube River, travelling on a collective Paraguayan visa.
She was supposed to pick up the Kladovo Group.
Hilda הילדה Orion's 726 passengers, were crammed on board, agreed to wait until visas for the Kladovo Group had been attained, and they waited for almost a month.
Hilda הילדה Orion was frozen to the pier and unable to sail, most of the members of the drunken crew had left, the fresh water was frozen, they were almost out of food, two passengers were nearing the ends of their pregnancies and, if something had not been done immediately, the passengers intended "to inform the world that they were being held in bondage under inhuman conditions" in Balchik Балчик.

In October, 1939, a month after the outbreak of World War II, Rachel Zakai, with 12 other members of קיבוץ ד, boarded Hilda הילדה Orion at Bratislava, for the voyage down the Danube River.

Rachel Zakai and the 12 members of קיבוץ ד who were captured by the British when Hilda הילדה Orion was intercepted, were interned at Atlit Detention Camp מחנה ההסגר בעתלית, and released in August, 1940.
