Well done that is correct on both counts, the comment 'we need several little Unwins' was a fine tribute to a very brave man. http://en.wikipedia.org/wiki/Edward_Unwin
The other men with him trying to keep the pontoons afloat were;
Midshipmen George Drewry (20) and Wilfred Malleson (18), Able Seaman William Williams (34), Seaman George Samson (26) and Sub-Lieutenant Arthur Tisdall (24) from the Royal Naval Division (RND). Of these men, only Williams died during the landing. Samson was severely wounded the following day. On his return to Scotland he was handed a white feather while wearing civilian clothes. Tisdall was killed on May 6 when the 6th (Hood) Battalion of the RND, made its advance along Kanli Dere during the Second Battle of Krithia. Drewry, Samson and Williams had come from the Hussar along with Unwin. Malleson, who died in 1975, served on the battleship HMS Cornwallis.http://en.wikipedia.org/wiki/SS_River_Clyde
It was rather a shame the old ship could not have been preserved as a testimony to the men, but as in so many other cases the chance was lost.
Over to you Pb for the next question.
