Operation Nachshon

Significance

Operation Nachshon was the Haganah's first large-scale operation under Plan Dalet, aimed at breaking the Arab blockade of the Tel Aviv–Jerusalem road and resupplying the besieged Jewish community of Jerusalem. The operation failed to secure permanent control of the road, and subsequent efforts to hold the route also proved unsuccessful, ultimately forcing the construction of a makeshift bypass known as the Burma Road. Despite not achieving its primary objective, Nachshon had lasting organizational consequences: the units that participated later broke off to form the Harel Brigade, a formation that would play a significant role in the wider conflict. The operation illustrated the strategic centrality of the Jerusalem corridor during the civil war, where control of supply routes directly determined the viability of the city's Jewish population.
