During the 1948 Palestine war, Eldad continued to be active as a co-leader of Lehi.
Acting in this role, Eldad participated in September 1948 in ordering the assassination of Folke Bernadotte, a United Nations mediator, as he subsequently admitted.

During the war Eldad was critical of Menachem Begin's Irgun for them, as he thought, not fighting against the Israel Defence Forces during the Altalena Affair.
He was also critical of the IDF for not fighting harder to conquer Jerusalem's Old City, and critical of Lehi fighters who did not rush to fight in Jerusalem.
Towards the end of the war, Eldad disguised himself as a foreign journalist in order to sneak past Israeli military roadblocks and join the battle for Jerusalem.
