Hamilton found abundance of provisions and some war materials at Raphoe, where, waiting to rest his troops, he was joined by Lord Galmoy with eight hundred men, and determined to advance on Derry, when his progress was arrested by the arrival of a deputation that came to treat for its surrender. The party were well received, and a conference being arranged to take place within two days, on condition that he should approach no nearer than St. Johnstown, they departed highly satisfied with their reception. Hamilton proceeded to the appointed place, and being impressed with the importance of Derry to the Jacobite cause, offered them the most liberal terms:--"Life, liberty, property, and protection, on condition that the town would be surrendered at twelve o'clock next day. The terms were accepted, and awaited but ratification on both sides." In the mean time, the king had left Dublin on the 8th of April, to take a view of the country. Hearing of the victory at Cladiford, he directed his course to that place, and arrived at the camp on the 18th, on the very hour that Hamilton was in conference with the delegates from Derry. De Rosen, perhaps, jealous of Hamilton's success, or wishing to gain credit with the king, represented to him that his presence before Derry would cause its gates to be at once thrown open, and prevent unnecessary delay, so he prevailed on him to make the experiment. Avoiding the place of conference, he took a circuitous route, and appearing before the town, summoned it to surrender. The "defenders," taking this sudden appearance of the king at such a time as an act of treachery on the part of Hamilton, answered the demand by a cannon-shot, which killed an officer by his side, and caused him to retire in shame and confusion. The consequence is easily foreseen. The treaty about to be ratified was broken off; the alarm was sounded throughout the rebel ranks; the "defenders" determined on more stern resistance; a siege was ordered by the king, and under escort of De Rosen, he returned to Dublin to meet his Parliament, which had been convoked for the 7th of May.
