The hostility towards the police in Sheffield was further aggravated when the area covered by the force was extended outwards from the centre of town, which caused much resentment by the law breakers of the districts. One of the men employed as a night watchmen in 1838 was a man called Joseph Straw, who was numbered watchman number fifty three on the new force. Six years later, Straw was enjoying patrolling Sheffield at night, his beat being along Westbar, Gibraltar Street and several other adjoining streets around. He particularly enjoyed having the town to himself, especially in the month of April when the weather was becoming more clement.
The night of Tuesday 30 April 1844 was one such balmy, moonlit night and Straw was standing at the bottom of Furnace Hill when he saw a man, well known to the police called Mark Roberts. He was twenty one years of age, and he and a companion were coming out of a beerhouse in Bower Street. Just then a young woman passed Straw and he heard Roberts call out to her. However the woman did not appear to want to speak to him, or acknowledge him in any way. In retaliation, Roberts crossed over the road towards the girl and struck her very hard on her back and then as she fell, he punched her in the stomach.
Straw immediately went over to the couple and asked him ‘what have you done that for?’ Roberts simply answered that ‘she has been asking for it.’ The watchman then asked the stricken girl what her name was and she replied that it was Martha Cartledge. However when he asked her if he should take Mark Roberts in charge, she simply shrugged her shoulders. Straw angrily told Roberts to be on his way, but man would not move. Without any warning Roberts then punched Straw, before running off. The watchman managed to pursue him, at the same time taking out his rattle, which he sounded to call for help. Then Roberts ran down a passage leading out of Gibraltar Street into Cherry Tree Yard before he tripped and crashed to the ground.
Straw stood over him and ordered him to get up, at the same time continuing to rotate his rattle for help. By this time Straw was getting quite annoyed at his prisoner and grabbing Roberts around the collar, he roughly forced him onto his feet. Almost dragging him along at this stage, the two men were proceeding out of the yard when Roberts suddenly sat down on some steps. Once again the watchman stood over him and told him to get up, just as the prisoner lunged at him. That was when Straw felt a stabbing pain in his back, at the same time feeling a trickle of blood running down his back and legs. Thankfully, by this time two other police officers arrived, summoned by their colleagues rattle.
They were Sergeant Revill and Police Constable Lorimer. The sergeant quickly marched the culprit off to the Town Hall, whilst Lorimer accompanied the injured watchman to the surgery of Mr Henry Payne. The surgeon examined his wound and found it bleeding profusely, so he stitched it up as quickly as he could. The injured man was then taken back to his lodgings in Trippet Lane, Sheffield where he was put to bed by his wife. For two days his life was despaired of, as Mr Payne valiantly continued to attend to Straw. Thankfully by the third day, the surgeon had hopes that his patient would eventually recover.
By this time it had been established that his attacker was indeed Mark Roberts, who was very well known to the police force. He had been involved in a lot of illegal activities in Sheffield for some years. He was also known to be very antagonistic towards police officers and had a history of violence against them. Consequently on Thursday 2 May, Roberts was brought before the magistrates, charged with the stabbing offence. However he was simply remanded until Tuesday 7 May 1844, due to the fact that the watchman was still too ill to give his own evidence. After a further remand, the case was finally heard on Tuesday 14 May 1844.
In court, Mr Raynor acted as prosecution as he described the crime for the court. He told them that as a result of his injuries, Joseph Straw had been confined to his bed for nine full days after the attack. He then held up the bloody clothing that the injured man had been wearing at the time, which were quite shocking to see. Two witnesses called Thomas Cooper and Samuel Vickers who had been passing, confirmed the events of the night. A third witness John Fowler described how he saw the prisoner sitting on some steps, before seeing him put his hand in his trouser pocket and draw out something, which was ‘long and shiny.’ The witness spoke of his horror when he saw the man plunge the blade into the officer’s back.
Fowler was asked by one of the jury if he could have been mistaken, but he shook his head as he replied that he could see everything as the moon was so bright. The next to give evidence was the surgeon Mr Henry Payne, and he told the court how Joseph Straw was brought to his surgery by several persons. When his clothes were removed, the surgeon stated that he found an incision about three inches below the injured man’s left shoulder blade, which was bleeding profusely. Thankfully, the surgeon said that he had managed to stop the bleeding, before dressing the wound and sending his patient home. Mr Payne concluded that he considered the wound to be a dangerous one and that for some time, he felt that the watchman’s life was in great danger.
Martha Cartledge was next to testify, and she told the court that she was a single woman who lived on Trinity Street, Sheffield. She knew the prisoner because he had been going out with another young woman that she was acquainted with, called Elizabeth Ashton. The witness told the bench that on the night in question, she had gone out to get some supper, when she had been confronted by Mark Roberts. He appeared to be very angry with her and pulled her about, all the time speaking to her using very indecent language. The witness stated that when the watchman asked her if he should take the prisoner into custody, she had simply told him to make the prisoner go about his own business.
Roberts had arrogantly told Straw ‘I can beat a dozen watchmen like you’ as he struck him. However, Cartledge admitted that she had gone looking for some help at that point and therefore she didn’t witness the actual stabbing. The prisoners defence, Mr Palfreyman ably cross examined all the witnesses, but even he had to admit that the case against Mark Roberts was hard to disprove. He pointed out nevertheless, that Roberts had acted on the spur of the moment and there had been no clear intentions behind his actions. Even Joseph Straws solicitor, Mr Hunter was forced to admit that he did not suppose that Roberts had intended to actually kill his client.
The magistrate Rev J Hand considered the case very carefully before committing the prisoner to take his trial for ‘intending to do grievous bodily harm’ and he was removed. Accordingly, Mark Roberts appeared at the Yorkshire Assizes on Tuesday 16 July 1844 in front of judge Mr Justice Cresswell. The case was prosecuted by Mr Smith who laid out the events for the jury. The same witnesses gave their evidence as before, and the jury had no other option but to find Mark Roberts guilty of ‘feloniously stabbing, cutting and wounding Joseph Straw.’ Mr Justice Cresswell spoke about the vicious nature of the attack on a defenceless watchman, before sentencing the prisoner to fifteen years transportation.
