Note 11 — Ballads of the Revolution.[1]
Reading edition
“As Barton and his men approached the gate, a sentinel hailed them twice, and then demanded the countersign. ‘We have no countersign to give,’ Barton said, and quickly added: ‘Have you seen any deserters here to-night?’ The sentinel was misled by this question, supposing them to be friends ... until his musket was seized, and himself bound and menaced with instant death if he made any noise.”—Idem.
