For distinguished conduct in battle, engagements of Vera Cruz, 21- 22 April 1914. Eminent and conspicuous in command of his battalion, Lt. Castle was in the fighting of both days, and exhibited courage and skill in leading his men through action. In seizing the customhouse, he encountered for many hours the heaviest and most pernicious concealed fire of the entire day, but his courage and coolness under trying conditions were marked.
