Line was formed and the detachment started back, Danny Grin and two sailormen acting as a rear guard against possible attack.

Arrived at the post-office Trent, accompanied by Cantor and the latter's guards, hurried off in search of the commanding officer of the shore force.

Fifteen minutes later Lieutenant Trent returned.

"I was sustained," he informed Dave and Dan. "It was tough, but the commanding officer directed me to send Cantor under escort back to the 'Long Island,' with a brief report stating why that officer was placed in arrest."

There followed more waiting, during which the sound of individual firing over the city became more frequent. Cantor's guard returned from the "Long Island," with word that Captain Gales had ordered that officer in arrest in his own quarters.

At last orders for Trent's detachment arrived.

"We are to push on into the city," Trent informed his ensigns. "Twenty more 'Long Island' men will reach us within three minutes. We are to silence snipers, and kill them if we catch them red-handed in firing on our forces. Above all, we are directed to be on the alert for any Americans or other foreigners who may be in need of help. We are likely to have a busy night."

Then, turning to his men, he added:

"Fall in by twos! Forward, march!"
