The Egyptians made the best of the time factor as per historian V. B. Lutsky [ru]. In October 1831, Ibrahim launched a military campaign. Around two to three weeks later, after not having encountered serious resistance, Egyptian troops occupied Gaza, Jaffa, Haifa, and, at the end of November 1831, advanced on Akka, the fortress which had once barred Napoleon's path in 1799. Following a six-months long siege, Akka fell to the Egyptians. By this time, the main Egyptian forces were far away in the north.[2]
