Foreign their gallant conduct at the attack on the Block-house at Dewan-Giri, in Bhootan, on the 30th of April, 1865. The Block-house, which was loop-holed, was the key of the enemy"s position. Seeing no Officer of the storming party near him, and being anxious that the place should be taken immediately, as any protracted resistance might have caused the main body of the Bhooteas to rally, the British force having been fighting in a broiling sun on very steep and difficult ground for upwards of three hours, the General in command ordered these two Officers to show the way into the Block-house.
They had to climb up a wall which was 14 feet high, and then to enter a house, occupied by some 200 desperate men, head foremost through an opening not more than two feet wide between the top of the wall and the roof of the Block-house.
Both of them were wounded. He is buried at Kensal Green Cemetery.
