Marcus's role in the War of Independence is revised by Shamir's daughter

Yael Driver, the daughter of Maj.-Gen. Shlomo Shamir, has published an account of the 1948 War of Independence that challenges the standard narrative surrounding David “Mickey” Marcus. Driver contends that her father, who recruited Marcus in January 1948, was the primary figure in the American officer's integration into the fledgling Israel Defense Forces. She argues that Marcus served as an adviser and unifier rather than the supreme commander portrayed in the 1966 film Cast a Giant Shadow.

The distinction matters because it clarifies how a paramilitary force transformed into a regular army. Driver states that Marcus’s most important contribution was converting soldiers who lacked respect for hierarchy into a structured organization. Approximately 30,000 Jewish soldiers were veterans of the British Army, but the Palmach, a group of 4,000 to 5,000 fighters, operated informally. Marcus noted that “every platoon commander is a general” within these ranks. He adapted US Army manuals into Hebrew, creating the basis for future IDF training codes.

Shamir, who served in the Jewish Brigade of the British Army, was tasked by David Ben-Gurion in October 1947 to find an American general. He met Marcus in New York in November 1947. The pair reviewed a list of 24 candidates and narrowed it to Maj.-Gen. Ralph C. Smith. Smith declined the offer because his US Army pension would be forfeited. Marcus, who had no such conflict of interest, accepted the position for a salary of $750 per month, plus expenses.

Marcus arrived in Palestine in early 1948. He was appointed Supreme Commander of the Jerusalem Front on May 28, 1948. Driver describes this as a declarative appointment that lasted only two weeks before Marcus died in an accident on June 11, 1948. She notes that the IDF had not yet introduced formal ranks when Marcus took the post. Ben-Gurion determined ranks two weeks after Marcus's death. Appendix 1 to IDF General Staff Ordinance No. 10, dated August 11, 1948, listed the first 12 major-generals effective retroactively from August 1, 1948. Marcus was not on that list.

The film Cast a Giant Shadow credited Marcus with creating the road that lifted the siege on Jerusalem. Driver says the main road was controlled by the Arab Legion at Latrun. The Palmach’s Har’el Brigade forged a dirt road, but it was too narrow for heavy convoys. The 7th Brigade then built Route 7, also known as the Burma Road. Driver states that Shamir’s 1994 book attests Marcus did not participate in planning or building Route 7. He did not speak or write Hebrew and did not appoint his own staff.

Driver concludes that Marcus was a vital adviser who helped unify the command structure. She emphasizes that his personality and physical fitness helped him win over soldiers who initially had little respect for military discipline. The historical record now distinguishes between the ceremonial title given to Marcus and the practical work of building the IDF's foundational regulations.
