In 1944 the Royal Navy succeeded in modifying one of its conventional submarines, Seraph, to match the performance of the radically new Type XXI fast boats that intelligence showed Germany was developing.1 If the enemy had succeeded in getting the Typ XXI to sea in large numbers, they would have revolutionised submarine warfare, and severely tested Allied anti-submarine defences.
A selection of eclectic poetry and prose on various topics which will hopefully entertain, inspire and stimulate the mind.
