The President of the United States of America takes pleasure in presenting the Silver Star to Sergeant Frank Krywicki (MCSN: 300745), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Platoon Sergeant of an Assault Demolition Platoon of Headquarters Company, Second Battalion, Twenty-fourth Marines, FOURTH Marine Division, in action against enemy Japanese forces on Iwo Jima, Volcano Islands, 4 March 1945. After leading one of his assault squads to a front line rifle company pinned down by heavy enemy fire from a series of caves, Sergeant Krywicki directed his men in hurling satchel charges into the caves. Each time the charges were thrown into one of the caves the enemy pulled the fuse from the charges, rendering them harmless and, when a charge with a shorter fuse was thrown into the cave, it was hurled out of the cave and exploded immediately, killing the demolition man and seriously wounding Sergeant Krywicki. Although suffering from great pain, he prepared another satchel charge and threw it into the cave and succeeded in killing all Japanese within. By his courage, aggressiveness and determination, Sergeant Krywicki greatly aided his squad in completing their mission, and his conduct throughout upheld the highest traditions of the United States Naval Service.
