Of the precise origin of the riot it is difficult to speak with certainty. It has been stated that it originated in a dispute between a Maltese and a native coachman or donkey-boy, in which the Maltese, being beaten with a stick, retaliated with his knife, and, according to one account, killed his adversary. Another version is that two natives attempted to break into the shop of a Maltese with whom they had previously quarrelled, and were violently resisted by the owner. Both accounts are involved in doubt, and the better opinion is that whatever may have been the origin of the alleged quarrel, it was only a pretext for what was to ensue. Anyhow, about the time last mentioned, Mr. Cookson, the British Consul, was summoned by the local police to assist in quelling a disturbance between Maltese and natives in the quarter of the Caracol Labban, a police-station in the Rue des Sœurs. He found there the Governor and Sub-Prefect of Police, and, after waiting more than an hour, under the impression that they had succeeded in calming the excitement, Mr. Cookson returned to the Consulate. This was not, however, until he had been struck by one of the stones which were flying about.

About 3 p.m. he found a messenger, purporting to come from the Governor, to summon him with all the other Consuls to a meeting at the same Caracol as before.

There is good reason to believe that no such request was ever made by Omar Pasha Loutfi, and that the messages sent were part of a preconceived scheme to decoy the Consuls into the streets, where they would be in the power of the mob. It is a singular thing that there were considerable intervals of time between the delivery of the messages, not warranted by the positions of the different Consulates, as if the intention was for the Consuls to arrive separately. Mr. Cookson, accompanied only by a janissary in uniform, drove immediately towards the Caracol. He found marks of recent conflict in the streets and groups of excited natives moving about. On approaching within about ninety yards of the Caracol, at a place where four roads met, he was first assailed with stones and then felled to the ground with a blow from a "naboot." When the Consul recovered consciousness, he was lying in the street surrounded by a crowd, one or two members of which, including a native officer, were trying to protect him, whilst others were striking at him. Fortunately he was able to escape with his life to the Caracol, where he remained till about 4 p.m., when he was brought by a circuitous route to the Consulate.[12]

It has been stated that the inaction of the police at the different Caracols was due to the fact that the day previous all the officers and sub-officers in charge had been convoked, and told that the men were to remain at their posts under any circumstances, without interfering even in the event of an outbreak happening.

Almost at the same time and place, the other members of the Consular body, as they arrived on the scene, were similarly attacked.

All this time the Governor was at the door of the Caracol, giving orders to the mustaphazin (military police) to disperse the mob, though his orders were never executed. In fact, the mustaphazin were quite beyond his control, and at times openly cursed and reviled him when he tried to interfere on behalf of the Europeans.

Whilst the fighting went on, the Arabs, the police, and the soldiers occupied their time in breaking open and plundering the shops and houses on the line of route, tearing down doors and shutters, and using the materials as well as the legs of tables and chairs as weapons of offence.

The rioting gradually extended up the Rue des Sœurs, towards the Place Mehemet Ali (the great square), the Europeans here and there firing at times from the terraces and balconies of the houses, and the soldiers and the mob replying with firearms and stones.

At an early period of the fray, one of the mustaphazin was killed by a shot from a house, and his body being taken to an adjoining Caracol, his comrades became so exasperated, that they butchered every European who sought refuge there.

In the streets, the conduct of the mustaphazin was almost equally bad. When they did interfere, they did so in a half-hearted, indifferent manner. In the great majority of cases, where they did not join in the killing themselves, they encouraged their countrymen to do so. There is reason to believe that the mustaphazin did a large proportion of the killing, as they were armed with sword-bayonets. The natives, on the other hand, had in most cases only heavy sticks, with which they stunned and bruised their victims.
