 It was madness to dare the dense murder that spewed from  those ghastly machines.
 (Only those who have danced to its music can know what the mitrailleuse means.)
  But the bridge on the Aisne was a menace; our safety demanded its fall:
   "Engineers, -- volunteers!" In a body, the Royals stood out at the call.

Death at best was the fate of that mission -- to their glory not one was dismayed.
A party was chosen -- and seven survived till the powder was laid.
And they died with their fuses unlighted. Another detachment!  Again
 A sortie is made -- all too vainly. The bridge still commanded the Aisne.
                                                                                --Herbert Kaufman
                                                                                                                       TO # 8
