Input: Consider Input: Question: How many times was the person who sent 15,000 troops married? Passage:Halleck's plan, finalized in January 1864, called for Banks to take 20,000 troops up from New Orleans to Alexandria, including the 47th Pennsylvania Infantry, the only regiment from the Keystone State to fight in this campaign, on a route up the Bayou Teche (in Louisiana, the term bayou is used to refer to a slow moving river or stream), where they would be met by 15,000 troops sent down from Major General William T. Sherman's forces in Vicksburg, Mississippi, and under the command of Brigadier General A.J. Smith. Smith's forces were available to Banks only until the end of April, when they would be sent back east where they were needed for other Union military actions. Banks would command this combined force of 35,000, which would be supported in its march up the Red River towards Shreveport by Union Navy Rear Admiral David Dixon Porter's fleet of gunboats. At the same time, 7,000 Union troops from the Department of Arkansas under the command of Major General Frederick Steele would be sent south from Arkansas to rendezvous with Banks in his attack on Shreveport, and to serve as the garrison for that city after its capture.

Input: Consider Input: Question: How many other books did Baen Books publish the year it published The Complete Compleat Enchanter? Passage:The Complete Compleat Enchanter is an omnibus collection of five fantasy stories by Ametican authors L. Sprague de Camp and Fletcher Pratt, gathering material previously published in three volumes as The Incomplete Enchanter (1941), The Castle of Iron (1950), and Wall of Serpents (1960), and represents an expansion of the earlier omnibus The Compleat Enchanter, which contained only the material in the first two volumes. The expanded version also differs from the previous omnibus by omitting its afterword, de Camp's essay "Fletcher and I". The omnibus is the first edition of the authors' Harold Shea series to be complete in one volume. It has appeared under three different titles. It was first published in the UK in paperback by Sphere Books in 1988 under the title The Intrepid Enchanter and with a foreword by Catherine Crook de Camp. The first US edition appeared under the title The Complete Compleat Enchanter, and replaces the foreword with a preface by David Drake. That edition was published by Baen Books in 1989, and has been reprinted a number of times since. Orion Books published an edition in the UK under the title The Compleat Enchanter in 2000 as volume 10 of their Fantasy Masterworks series. The stories in the collection were originally published in magazine form in the May 1940, August 1940 and April 1941 issues of Unknown, the June 1953 issue of Beyond Fantasy, and the October 1954 issue of Fantasy.
