“Impossible, sirs:  ye have been asleep on your posts, or ye must have seen him.  He passed this way, and could not have escaped your observation had ye been attentive to your duty.”

“Well, sure, and your honour knows bist,” rejoined the first sentinel; “but so hilp me St. Patrick, as I have sirved man and boy in your honour’s rigimint this twilve years, not even the fitch of a man has passed me this blissed night.  And here’s my comrade, Jack Halford, who will take his Bible oath to the same, with all due difirince to your honour.”

The pithy reply to this eloquent attempt at exculpation was a brief “Silence, sirrah, walk about!”
