However, it is probable that they may be able to do so until an Austrian force comes up, and tries to relieve them.
"From what we hear, two armies have already entered Bohemia, and we may expect that our first battle will not be far distant." "Do we block the only line of retreat, sir ?" Fergus asked.
"No, indeed.

We do not absolutely close the direct road, but our position, and that of Marshal Schwerin facing Koeniggraetz, so menaces their line of retreat that they dare not venture from their shelter; and our cavalry render it impossible for any supplies to be thrown in, unless the convoy is supported by an army.

There are, we know, paths across the hills by which infantry might effect a passage; but as there is nowhere a place for them to retire to, we should easily overtake them and force them to surrender.
