Incapillo is a Pleistocene-age caldera – a depression formed by the collapse of a volcano – in La Rioja Province, Argentina. It is part of the southernmost volcanic centre in the Andean Central Volcanic Zone (CVZ). Subduction of the Nazca Plate beneath the South American Plate is responsible for most of the volcanism in the CVZ. Volcanism commenced in the Incapillo region 6.5 million years ago, forming the high volcanic edifices of Monte Pissis, Cerro Bonete Chico and Sierra de Veladero. Incapillo is known to have erupted the Incapillo ignimbrite 0.52 ± 0.03 and 0.51 ± 0.04 million years ago; this has a total volume of about 20.4 cubic kilometres (4.9 cu mi). A caldera with dimensions of 5 by 6 kilometres (3.1 mi × 3.7 mi) formed during the eruptions. Later volcanism generated more lava domes within the caldera and a debris flow in the Sierra de Veladero. The lake within the caldera may overlie an area of ongoing hydrothermal activity.

The Battle of Villers-Bocage took place in German-occupied France on 13 June 1944 during World War II. Following the D-Day landings on 6 June, the Germans established defences in front of Caen. The British attacked in an attempt to exploit a gap in the German defences west of the city. They reached Villers-Bocage without incident in the morning but were ambushed by Tiger I tanks as they left the town and numerous tanks, anti-tank guns and transport vehicles were destroyed. The Germans then attacked the town but were repulsed. The British withdrew west of Villers-Bocage that evening and repulsed another attack the next day. The British conduct in the battle was controversial because their withdrawal marked the end of the post–D-Day "scramble for ground" and the start of an attritional battle for Caen. Some historians wrote that the British attack was a failure caused by a lack of conviction among some senior commanders; others judged the British force to be insufficiently strong for the task.
