Soon after this, the Post-office having learnt that the public-house in the London Wall was the resort of highwaymen, it was closely watched. One of Hawkins’ gang became alarmed, and was on the point of bolting to Newcastle when he was arrested. He was hesitating whether or not he should confess, when he found that he had been forestalled by an associate, who had already given information to the Post-office, and he also made a clean breast of it all. The rest of the gang were taken at their lodgings in the Old Bailey, but not without a fight, and committed to Newgate. Hawkins tried to set up an alibi, and an innkeeper swore that he lodged with him at Bedfordbury on the night of the robbery; but the jury found him guilty, and he was hanged at Tyburn, his body being afterwards hung in chains on Hounslow Heath. The defence of an alibi was very frequently pleaded by highwaymen, and the tradition of its utility may explain why that veteran and astute coachman, Mr. Weller, suggested it in the case of ‘Bardell _v._ Pickwick.’ In one genuine case, however, it nearly failed, and two innocent men were all but sacrificed to mistaken identity. They had been arrested for having robbed, on the Uxbridge road, a learned sergeant-at-law, Sir Thomas Davenport, who swore positively to both. His evidence was corroborated by that of Lady Davenport, and by the coachman and footman. Also the horses ridden by the supposed highwaymen, one a brown and the other a grey, were produced in the Old Bailey courtyard, and sworn to. Yet it was satisfactorily proved that both the prisoners were respectable residents of Kentish Town; that one, at the exact time of the robbery, was seated at table dining at some club anniversary dinner, and never left the club-room; that the other was employed continuously in the bar of a public-house kept by his mother. It was proved too that the prisoners owned a brown and a grey horse respectively. The Judge summed up in the prisoner’s favour, and they were acquitted. But both suffered severe mental trouble from the unjust accusation. A few years later the actual robbers were convicted of another offence, and in the cells of Newgate confessed that it was they who had stopped Sir Thomas Davenport. [Illustration: MACLANE.]
