While the troops worked these five guns and the three captured in Southwell's first attack Jack Stilwell was sent off on horseback at full speed with an order for the landing of the heavy guns and mortars from the fleet. The news of the attack on Montjuich and the retreat of the Spanish column spread with rapidity through the country, and swarms of armed peasants flocked in. These the earl dispersed among the ravines and groves round the city, so as to prevent any parties from coining out to ascertain what was going on round Montjuich, and to mask the movements of the besiegers.

Velasco appeared paralyzed by the energy and daring of his opponent, and although he had in hand a force equal if not superior to that which Peterborough could dispose of, he allowed two days to pass without attempting to relieve Montjuich. In those two days wonders had been performed by the soldiers and sailors, who toiled unweariedly in dragging the heavy guns from the landing place to the hill of Montjuich. The light cannon of the besiegers had had but little effect upon the massive walls of the fortress, and the Prince Caraccioli held out for two days even against the heavier metal of the mortars and siege guns that were quickly brought to bear upon him.
