Dr. Wassell was assigned to duty in Java caring for wounded officers and men of the cruisers Houston and Marblehead which had been in heavy action in the Java seas. When the Japanese advanced across the island, it was decided to evacuate as many as possible of the wounded to Australia. But about twelve of the men were so badly wounded that they could not be moved. Dr. Wassell remained with these men, knowing that he would be captured by the enemy. But he decided to make a desperate attempt to get the men out of Java. He asked each of them if he wished to take the chance, and every one agreed. He first had to get the twelve men to the sea coast-fifty miles away. To do this, he had to improvise stretchers for the hazardous journey. The men were suffering severely, but Dr. Wassell kept them alive by his skill, and inspired them by his own courage. On the sea coast, he embarked the men on a little Dutch ship. They were bombed and machine-gunned by waves of Japanese planes. Dr. Wassell took virtual command of the ship, and by great skill avoided destruction, hiding in small bays and inlets. A few days later, Dr. Wassell and his little flock of wounded men reached Australia safely.
