In December, 1587, he was employed, in concert with Sir John Gilbert and Lord Bath, in levying a force of 2000 foot and 200 horse in Cornwall and Devon. Exeter claimed exemption on account of its heavy expenses for the defence of its trade against Barbary corsairs. By the beginning of 1588 the immediate fear of attack had abated. The invasion was thought to have been put off. Ralegh took the opportunity to visit Ireland. There he had both public and private duties. He retained his commission in the army. Moreover, he was answerable, as a Crown tenant, for twenty horsemen, though his charges for them were refunded. Thus, in March, 1588, an order was made for the payment to him of £244 for the previous half year. Always he had his estate to put in order, and functions connected with it to perform. According to the local records, he served this year the office of Mayor of Youghal. During a considerable portion of the term he must have been an absentee. In Ireland the news reached him that the Armada had started or was starting. Hastening back he commenced by mustering troops in the West, and strengthening Portland Castle. But his own trust was in the fleet. In his _History of the World_ he propounds the question whether England without its fleet would be able to debar an enemy from landing. He answers by showing how easily ships, without putting themselves out of breath, will outrun soldiers marching along the coast. The Spaniards in July, 1588, could, in his opinion, but for the English ships, have chosen a landing-place with no sufficient army at hand to resist them. The Armada might have failed, he admits, against the choice troops gathered about the Queen. He did not believe in the ability of the remainder round the coast to encounter an army like that which the Prince of Parma could have landed in England. His advice had its weight in inducing Elizabeth to fit out the fleet, which did noble service under Howard of Effingham. [Sidenote: _Against 'Grappling'._]
