EFFECTS OF THE EXPLOSION. 77 



the tree, causing it to fall just on the other pole of 

 the battery and so producing the explosion. 



With the sentry, who was standing on the breast- 

 work of the ravelin when the explosion occurred, it 

 had fared worse. I found him on the other side of 

 the pit lying on the ground apparently dead, beside 

 him his gun buried half barrel length in the earth 

 bayonet forward. The powerful draught, caused by 

 the mine exploding in the open pit. had evidently

 of the mine. Fortunately however he had clutched his

 days again fit for service. The Kiel military doctor, 

 who had hurried to Friedrichsort on the announcement 

 of the appearance of the Danish squadron, and was 

 crossing the drawbridge at the moment of the explosion,

 vehicle into the rampart -moat and had received a few 

 contusions. The cook too, who was just carrying 

 up the steps of the ground -floor a bowl of soup and 

 was thrown down by the explosion, was severely 

 scalded.
