beleaguer

To besiege; to surround with troops.

I have read in some old marvellous tale, / Some legend strange and vague, / That a midnight host of spectres pale / Beleaguered the walls of Prague. // Beside the Moldau's rushing stream, / With the wan moon overhead, / There stood, as in an awful dream, / The army of the dead.

To vex, harass, or beset.

To exhaust.
