HMS COSSACK (THIRD of the NAME)
The third vessel to bear the name HMS Cossack was reclassified as a Third-Class Cruiser shortly after completion, having proved too slow for front-line fleet duties and regarded as an indifferent sea boat. She was one of six cruisers constructed by J. & G. Thomson of Clydebank, Glasgow.
