“Ay, sir—a letter proposing an exchange of prisoners. This is the General’s reply, and he bade me say he earnestly hoped you would agree to the second proposal he makes.”

Waller read the letter thoughtfully.

“I will write a reply,” he said at length, “and in the absence of your brother will send it by Lieutenant Harford, who shall accompany you on your return. I see, Sir Ralph writes from Wells; both you and your horse will need rest and refreshment after such a ride. Lieutenant Harford will see that you are well cared for.”

“Shall I return for your reply, sir?” asked Gabriel.

“Come for it at sunrise to-morrow,” said Waller, glancing again at the letter. Then, looking up at Dick Heyworth, “I would fain comply with Sir Ralph’s request could I consult my personal wishes, but I am bound to think only of the Cause. I will wish you good-night, sir.”

It only remained for Dick Heyworth to bow and withdraw, but Gabriel noted his look of annoyance as they entered the adjoining room, where the remains of the officers’ supper were still on the table.

“’Tis ever ‘the Cause, the Cause,’ with you Parliament folk,” he said, shrugging his shoulders. “Now if our two Generals could have met there might be some hope of making an end of the war.”

“Was that your errand?”

“That and the reply as to the exchange of prisoners. You had best not tell it in Gath, however. Sir Ralph Hopton, as you doubtless know, was an old friend of your General’s, and they served together in the German wars. He had a great wish to meet him and discuss this accursed civil strife.”

“Of what avail would that be,” said Gabriel, “when the King will never offer terms that can be accepted, and when Parliament places no confidence in his promises.”
