bakery employed 25 workers and had one production line that turned out 8,500 loaves per day. It delivered bread to stores in two trucks and a horse and wagon. During World War II, the bakery contracted to supply bread to the British army, necessitating the purchase of large American-made ovens that could turn out 540 loaves per hour. Angel's Bakery played a key role in feeding Jerusalem residents during the 1948 War of Independence. When Arabs lay siege to the city and attacked convoys that attempted to bring food and supplies through the narrow mountain pass from Tel Aviv, water and flour were in short supply. Fire trucks were employed to shuttle water to the bakery and "flour was swept up off the bakery floor". Angel's son Danny, who was a Haganah fighter defending the besieged Old City, recalled that the bakery would send bread in convoys to the fighters in the Old City and Mount Scopus, and hide guns and ammunition in the sacks of bread. One of the first horses used for the Jewish assault on the Arabs' Old City positions came from Angel's Bakery; its feet were wrapped in old flour sacks so the British wouldn't detect it. The bakery is so well known that it is even depicted in the popular children's book Soosie, The Horse That Saved Shabbat by Tami Lehman-Wilzig, illustrated by notable Israeli artist Menahem Halberstadt (published in the US by Kalaniot Books). New baking technologies In the 1950s Salomon's three sons, Avraham, Ovadia and Danny, assumed managerial positions; they became co-CEOs after Salomon's death in 1966. In 1958 Angel's Bakery moved to its present location in the Givat Shaul industrial zone at the corner of Beit Hadfus and Farbstein Streets. The site was chosen because it stood across the street from a flour mill. The Angel brothers built Israel's first flour silo and commissioned a Texas company to construct a 750-foot pipeline to convey flour directly from the mill to the silo to the bakery. Today this pipeline brings 120 tons of flour to the bakery daily. The invention, initially opposed by the Jerusalem municipality for being above-ground, won the Kaplan Prize for distinction in productivity and efficiency. Also in 1965, the brothers introduced new long ovens and kneading machines. That same year, they produced the country's first sliced bread and bread containing soy flour.
