quarter to ten
At nine , on the dot , you meet Hay at Sola Ranch . At nine-ten , the torpedoes take off . At quarter to ten , they arrive over their destination -- San Francisco and the surrounding territory . And quarter to ten , if things go correctly -- which they must ! -- is the minute that ends the Slavish invasion of America . At ten minutes to ten , five minutes after the torpedoes strike , our troops charge forward in general attack . God be with you , Lance !
