When united with the rebel "squadron," two thousand five hundred strong, he would dispose of a force of fifteen thousand veterans, and he moved at once to relieve the besieged mutineers. His cousin Frederic, however, had no desire to measure himself with the stadholder at such odds, and stole away from him in the dark without beat of drum. ”
