The two friends remained in almost breathless suspense awaiting the signal.

At last it was returned, and moving forward, they reached the gate.
"Here," whispered Harry to the sentinel, as he handed him the watch and money.
The man raised the little lantern near him, and looked at the bribe to see that it was all right.

"Pass on," he said.
As Harry and his friend passed the gate, the former perceived several forms flit across the darkness, and a suspicion of treachery instantly flashed through his mind.
"We are betrayed," he whispered to Alfred.
"No matter, let us push boldly forward," was the reply.
They had not moved ten paces before the command "Halt" given.
"Push on!" exclaimed Alfred, darting forward.
The two friends moved on at a rapid run, when a volley of musketry was fired at them.

Harry escaped unhurt and continued running at the top of his speed, and not until he had gone a considerable distance, did he discover that his friend was not with him.

It was, however, too late for him to turn back, and entering Chicago, he made his way through the city, and continued his journey.
At the fire of the Federals, Alfred received four wounds; and sunk without a word to the ground.
