   The Helfrich plan is simple and direct, based upon a minute knowledge of Indies waters: to strike & strike again & again at the Japanese supply lines. For most of his naval life, Java-born Admiral Helfrich has done nothing but study war with the Japanese. His Navy was designed for shifty, aggressive action within the narrow East Indian waters. In the first 54 days of war his ships and cooperating Dutch planes sank 54 Japanese vessels. "Ship-a-day Helfrich," the Dutch soon called him. His ideas dominated the enlarging and equipping of Java's main naval base at Surabaya, where heavy cruisers (but not battleships) can be fueled and repaired. For the Helfrich plan to succeed, Surabaya must be held. 23 February 1942, “Dutchman's Chance”, in TIME, archived from the original on 2008-03-07
