On the night of the 15th of April two columns of men were gathered at midnight in the street leading to the water-gate, a short distance to the right of the tower, the third column close to a gate some little distance to its left. Lieutenant Beatty was, with his party of marines, to join the landing force, but to their disappointment neither Condor nor the midshipmen were to take part in the sortie, as the little party of seamen were to be held in reserve. Sir Sidney Smith himself intended to take his place on the tower, whence he could watch the operations. Wilkinson and Edgar were to act as his aides-de-camp, the latter to carry messages to the Turkish officers commanding the two columns, while Wilkinson was to perform the same office to the central column.
