And it was for that purpose he had called the White Mice together . When Roddy arrived they had , subject to his approval , arranged their plan . From what Vicenti had learned , the assault on the fortress would be made at midnight . It was accordingly agreed that at nine o'clock , when it would be quite dark , they would blow open the wall . Roddy , McKildrick and Peter would dine together at Roddy 's house , and at eight , in the launch , would leave his wharf . Pedro , whose presence would assure General Rojas of the good intentions of the others , was directed to so arrange his departure from Miramar as to arrive by the shore route at the wharf in time to accompany them . And Vicenti , who had set his watch with McKildrick 's , was at once to inform General Rojas of what was expected to happen , and at nine o'clock , when the wall fell , to rush with him through the breach .
