Disciplined Egyptian artillery ultimately breached even Napoleon's unconquerable fortress. [fact]
This dramatic confrontation of two kinds of warfare, one disciplined and orderly, and the other characterized by reliance on the bodily strength and personal courage of the warriors was repeated thirty-three years later in the battle of Acre in 1832. This time it was the turn of the Egyptians led by Ibrahim Pasha to reveal signs of the new type of warfare: hierarchical subordination, Frederickian discipline, and machine-like order. His adversary 'Abdallah Pasha, Vali of Sidon, had closed himself up in the formidable fortress of Acre that Napoleon himself could not take some thirty years earlier. For six months Ibrahim besieged the city and it was constantly showered with shells. The Egyptian artillerymen fired literally thousands of shells and it was said that not a single house had escaped uninjured. Finally the city could stand the siege no longer and when on the night of 26/27 May 1832 the Egyptian engineers and artillerymen effectively improved their precision and succeeded in making four breaches in the wall, Ibrahim Pasha summoned his senior officers to discuss with them the plan of attack that would take place the following day.
XREF: Continues the earlier claim about Ibrahim's 1832 Syrian campaign capturing Acre; here adding the tactical detail that precision artillery, not numbers, cracked the fortress.
Builds on: "Ibrahim's 1832 Syrian campaign captured Acre, Damascus, and Horns."
