Approximately a few kilometres out of town, by the railway fence on the northern line of the water main from Umberumberka, an ice cream cart flying a Turkish flag was noticed and two men later identified as Gool Mohamed and Mulla Abdulla, were seen crouched behind a mound of earth.
The firing continued as the train trudged slowly passed with 20 or 30 shots being fired. The picnickers panicked and thrown into confusion when they seen people falling around them.
The train was brought to a halt further up the line to determine the number of the passengers injured,if not killed. Two people were killed and six wounded on the train, Alma Cowie aged 17 died instantly. William Shaw a foreman in the Sanitary Department was killed and his daughter Lucy was injured. Another 5 people were also wounded. Three of the victims were removed from the train and taken to the pumping station at the reservoir and medical men summoned from Broken Hill to attend to them.
Alfred Millard, a pipeline inspector was killed when he received a fatal wound to the head as he was cycling beside the train.
Constable Robert Mills received two bullet wounds during the pursuit.
Jim Craig the fourth fatality, was chopping wood in his back yard at the rear of the Cable Hotel when a stray Turkish bullet killed him during exchange of fire.
Soon after the attack Gool and Abdullah withdrew towards the west. During their attempted escape they came across and murdered Millard. By this time the police were in full pursuit, when they sighted the two running assassins they fired their guns above their heads in order to force them to surrender, but Gool and Abdullah returned fire and wounded Mills.
The murderous pair made their last stand at the top of a hill where they found refuge behind large rocks a few hundred yards west of the Cable Hotel.
Local militiamen, police, members of the rifle club and citizens spread out on the adjoining hills, there was an hour and half of heavy gun fire poured into the enemy's position, the Muslims returning fire with spirit but without effect, the stronghold was rushed where it was found that Mullah Abdulla was dead and Gool Mohammed so severely injured that he died in hospital a few hours later.
What was the motive behind the attack, it seems a miner found three statements beneath a rock at the "Turks" last stand written in Urdu (a language used by Afghan tribesman of the North-West Frontier Provinces around 1915). Two of the documents revealed the motives for attacking the picnic train; the third proved to be an application by Gool Mohammed to join the Turkish Army.
In neat writing Gool Mohammed wrote, "I kill your people because your people are fighting my country". Mullah Abdulla had been worried because of a recent court conviction for killing a sheep on private property, in his capacity as a Moslem official. On one hand there was a fiery young Afrida itching to strike a blow for Turkey; on the other a simple friendless old man ready to join forces against authority.
The whole city was incensed at the needless slaughter and looked for some means of reprisal. The Germans and the Turks were at war with the Allies: The German Club building stood empty in Delamore Street and by nightfall was in flames. Because the "Turks" were Moslems a crowd rushed to the camel camp, ready to vent its anger on the Islamic community, but the road was blocked by police and militia and the crowd dispersed.
