Question: How many months before the buildup to Knightfall did the death of Superman occur? Passage 1:Within the regular series, the buildup to "Knightfall" begins with a six-issue run in Batman #484-489 (September 1992 - February 1993), in which Batman (at the onset of a personal psychological mid-life crisis) is forced to deal, in rapid succession, with the returning villain Black Mask and his gang (who target Bruce Wayne and Lucius Fox), a crazed killer called Metalhead, and a sharpshooter assassin hired by an imprisoned mobster to murder Commissioner Gordon. Batman begins to feel that he has lost his edge, especially after his failure to capture Black Mask. He finds himself unable to meditate or even focus. As Bruce Wayne, he contacts holistic therapist Shondra Kinsolving for treatment. He also assigns Robin (Tim Drake) to train Jean-Paul Valley in detective work to aid them as an ally, hoping to guide Valley's brainwashing away from making him a villainous threat. Despite the advice of everyone in his life, including Dr. Kinsolving, Bruce refuses to rest and continues to pursue his self-imposed duty despite his worsening condition (although not explicitly noted as a cause, these events take place immediately after the death of Superman, Batman's peer, elsewhere in the DC Universe).

 Passage 3:After her acquisition by the U.S. Coast Guard she was converted for use as a buoy tender at the Bethlehem Shipyard in San Francisco. She was commissioned USCGC Magnolia (WAGL-328) on 19 October 1947. She was first assigned to U.S. Coast Guard Base Yerba Buena Island, San Francisco. Her primary duties there were aids to navigation (ATON), servicing light stations and lightships on the California coast, search and rescue, and law enforcement. From 28 to 29 April 1951 she assisted the Japanese MV Flyer. On 9 February 1960 she assisted the disabled MV Angelo Petri two miles south of the San Francisco Bar. On 5 June 1963 she assisted following the collision between the U.S. Navy Military Sea Transportation Service (MSTS) ship USNS Asterion (T-AF-63) and the Japanese merchantman MV Kokoku Maru and transported 19 crew members from the Japanese ship to San Francisco. From 21 to 24 June 1965 she escorted the damaged catamaran SV Judy Al 165 miles southwest of Eureka, California to that port as her hull was too damaged to permit towing. She then transferred to U.S. Coast Guard Base Tongue Point, Astoria, Oregon on 1 September 1965, and redesignated WLB-328. Her primary duties there were aids to navigation (ATON), search and rescue, and law enforcement. She also tended the Columbia River Lightship on the Columbia River Bar. On 6 December 1967 she escorted the distressed MV David E. Day, which had grounded on the Columbia River Bar. On 10 August 1968 she assisted following the collision between MV Seatrain Washington and SS Rose S 17 miles east of Cape Flattery, Washington in heavy fog. Magnolia was decommissioned on 13 August 1971. She was stored at U.S. Coast Guard Training Center (TRACEN) at Government Island, Alameda, California until sold.
