Fort Budapest was the Bar Lev Line fort that remained under Israeli control throughout the Yom Kippur War.
The Yom Kippur War began on October 6, 1973, when Egypt and Syria launched a surprise attack on Israel. On the Sinai front, Egyptian forces crossed the Suez Canal and attacked Israel’s network of Bar Lev Line fortifications. Most of those positions were captured, evacuated, or overrun.
Fort Budapest was the notable exception. It stood at the northern end of the line, near the Mediterranean coast and southeast of Port Fouad, rather than directly beside the canal. Its location on a narrow strip bounded by water and salt marshes made a ground assault difficult, while its garrison benefited from strong defenses and Israeli air support.
Egypt made two major attempts to take the fort, on October 6 and October 15. Both failed. “Fort Putzer” was also a real Bar Lev Line position, which makes it a plausible distractor, but Budapest was the only fortification to stay in Israeli hands for the entire war.
