But the event that really decided Gordon to withdraw his resignation was the unexpected return of Burgevine. That adventurer had proceeded to Peking after his dismissal from the command, and obtained some support from the American minister in pressing his claims on the Chinese. He had been sent back to Shanghai with letters which, although they left some loophole of escape, might be interpreted as ordering Li Hung Chang to reinstate him in the command. This Li, supported by the English commanding officer at Shanghai, had resolutely refused to do, and the feud between the men became more bitter than ever. Burgevine remained in Shanghai and employed his time in selling the Taepings arms and ammunition. In this way he established secret relations with their chiefs, and seeing no chance of Imperial employment he was not unwilling to join his fortunes to theirs. This inclination was increased by the belief that he might be able to form a force of his own which would give a decisive turn to the struggle, and his vanity led him to think that he might pose on the rebel side as no unequal adversary of Gordon, to whom all the time he professed the greatest friendship. These feelings arose from or were certainly strengthened by the representations made by several of the officers and men whom Gordon had dismissed from his army. They easily led Burgevine to think that he was not forgotten, and that he had only to raise his standard to be joined by many of his old men.
A fortnight before Gordon's resignation Dr Macartney--who had some time before begun his remarkable career in the Chinese service, and of whom Gordon himself said: "He drilled troops, supervised the manufacture of shells, gave advice, brightened the Futai's intellect about foreigners, and made peace, in which last accomplishment his _forte_ lay"--wrote to him, stating that he had positive information that Burgevine was enlisting men for some enterprise, that he had already enrolled 300, and that he had even chosen a special flag for his force. A few days later Burgevine, probably hearing of this communication, wrote to Gordon, begging him not to believe any rumours about him, and stating that he was coming up to see him. Gordon unfortunately believed in this statement, and as he wished to exhibit special lenience towards the man whom he had displaced in the command, he went bail for him, so that he retained his personal liberty when the Chinese arrested Burgevine's agent Beechy, and wished to arrest Burgevine himself. On 2nd August Burgevine threw off the mask. At the head of a band of thirty-two rowdies, he seized the new steamer _Kajow_ at Sungkiang, and with that vessel hastened to join the Taepings. The very day that this happened Gordon reached Shanghai for the purpose of resigning his command, but on the receipt of this intelligence he at once withdrew his resignation and hastened back to Quinsan. Apart from public considerations, he felt doubly bound to do this because Burgevine had not been arrested on his pledged word.
