Lorraine Campaign is a term used by U.S. Army historians to describe operations of the U.S. Third Army in Lorraine during World War II from September 1 through December 18, 1944.
 Official U.S. Army campaign names for this period and location are "Northern France" and "Rhineland".
 The term was popularized by the publication of a volume of the same name by the U.S. Army in 1950.
 As written by the volume's author:
Manila is an unincorporated community in Johnson County, Kentucky, United States.
 Manila's original post office opened on July 1, 1898 and was named in honor of the Battle of Manila Bay, which had occurred earlier that year.
 The community's ZIP code is 41238.
During World War II, Operation Grenade was the crossing of the Roer (Rur) river between Roermond and Düren by the U.S. Ninth Army, commanded by Lieutenant General William Hood Simpson, in February 1945.
In predicate logic, existential instantiation (also called existential elimination) is a valid rule of inference which says that, given a formula of the form formula_1, one may infer formula_2 for a new constant or variable symbol "c".
 The rule has the restriction that the constant or variable "c" introduced by the rule must be a new term that has not occurred earlier in the proof.
The perfect tense or aspect (abbreviated ' or ') is a verb form that indicates that an action or circumstance occurred earlier than the time under consideration, often focusing attention on the resulting state rather than on the occurrence itself.
 An example of a perfect construction is "I have made dinner": although this gives information about a prior action (my making the dinner), the focus is likely to be on the present consequences of that action (the fact that the dinner is now ready).
 The word "perfect" in this sense means "completed" (from Latin "perfectum", which is the perfect passive participle of the verb "perficere" "to complete").
The Battle of Fort Driant was a constituent battle in the 1944 Battle of Metz, during the Lorraine Campaign and the greater Siegfried Line Campaign.
 The battle was on occupied French territory between the forces of the United States Third Army under the command of General George S. Patton and the forces of Nazi Germany under General Otto von Knobelsdorff.
The VI Corps was activated as VI Army Corps in August 1918 at Neufchâteau, France, serving in the Lorraine Campaign.
 Constituted in the Organized Reserves in 1921, it was allotted to the Regular Army in 1933 and activated on 1 August 1940 at Fort Sheridan, Illinois.
 VI Corps took part in some of the most high-profile operations in World War II.
Ouvrage Bois-du-Four is a lesser work ("petit ouvrage") in the Fortified Sector of the Crusnes of the Maginot Line.
 The ouvrage consists of a single large combat block without an underground gallery system, and is located between "petit ouvrage" Mauvais-Bois and "gros ouvrage" Bréhain, facing Luxembourg.
 A planned expansion, never carried out, was intended to enlarge Bois-du-Four into a fully equipped "gros ouvrage".
 Bois-du-Four saw little action in either the Battle of France in 1940 or the Lorraine Campaign of 1944.
 It is preserved by the community of Villers-la-Montagne and may be visited.
The Société Normande de Peinture Moderne, also known as "Société de Peinture Moderne", or alternatively, "Normand Society of Modern Painting", was a collective of eminent painters, sculptors, poets, musicians and critics associated with Post-Impressionism, Fauvism, Cubism and Orphism.
 The "Société Normande de la Peinture Moderne" was a diverse collection of avant-garde artists; in part a subgrouping of the Cubist movement, evolving alongside the so-called Salon Cubist group, first independently then in tandem with the core group of Cubists that emerged at the Salon d'Automne and Salon des Indépendants between 1909 and 1911 (i.e., Albert Gleizes, Jean Metzinger, Fernand Léger, Robert Delaunay and Henri Le Fauconnier).
 Historically, the two groups merged in 1912, at the Section d'Or exhibition, but documents from the period prior to 1912 indicate the merging occurred earlier and in a more convoluted manner.
Ouvrage Bréhain is part of the Fortified Sector of the Crusnes of the Maginot Line, located near the community of Bréhain-la-Ville in the Meurthe-et-Moselle "département" of France.
 Bréhain is flanked by "petits ouvrages" Mauvais Bois and Aumetz.
 The "gros ouvrage" was equipped with long-range artillery, and faced the border with Luxembourg.
 It saw no major action in either the Battle of France in 1940 or the Lorraine Campaign of 1944.
 While not open to public visitation, it has been secured and is in relatively good condition when compared to other abandoned Maginot positions.
 A flanking casemate has been restored and may be visited.
