On 10th September all his plans were completed, and Colonel Stewart, accompanied by a strong force of Bashi-Bazouks and some black soldiers, with Mr Power and M. Herbin, the French consul, sailed northwards on five steamers. The first task of this expedition was if possible, to retake Berber, or, failing that, to escort the _Abbas_ past the point of greatest danger; the second, to convey the most recent news about Khartoum affairs to Lower Egypt; and the third was to lend a helping hand to any force that might be coming up the Nile or across the desert from the Red Sea. Five days after its departure Gordon knew through a spy that Stewart's flotilla had passed Shendy in safety, and had captured a valuable Arab convoy. It was not till November that the truth was known how the ships bombarded Berber, and passed that place not only in safety, but after causing the rebels much loss and greater alarm, and then how Stewart and his European companions went on in the small steamer _Abbas_ to bear the tale of the wonderful defence of Khartoum to the outer world--a defence which, wonderful as it was, really only reached the stage of the miraculous after they had gone and had no further part in it. So far as Gordon's military skill and prevision could arrange for their safety, he did so, and with success. When the warships had to return he gave them the best advice against treachery or ambuscade:--"Do not anchor near the bank, do not collect wood at isolated spots, trust nobody." What more could Gordon say? If they had paid strict heed to his advice, there would have been no catastrophe at Dar Djumna. These reflections invest with much force Gordon's own view of the matter:--"If _Abbas_ was captured by treachery, then I am not to blame; neither am I to blame if she struck a rock, for she drew under two feet of water; if they were attacked and overpowered, then I am to blame." So perfect were his arrangements that only treachery, aided by Stewart's over-confidence, baffled them. With regard to the wisdom of the course pursued in thus sending away all his European colleagues--the Austrian consul Hensall alone refusing to quit Gordon and his place of duty--opinions will differ to the end of time, but one is almost inclined to say that they could not have been of much service to Gordon once their uppermost thought became to quit Khartoum. The whole story is told very graphically in a passage of Gordon's own diary:--
