Question: Which hospital in England was founded in 1919 to treat for combat stress reaction victims? 

Context paragraphs:
Cassel Hospital: The Cassel Hospital was founded and endowed by Ernest Cassel in England in 1919.  It was initially for the treatment of "shell shock" victims.  Originally at Swaylands in Penshurst, Kent, it moved to Stoke-on-Trent during World War II.  In 1948 it relocated to its present site at No. 1 Ham Common, Ham.

John Patrick Spiegel: John Patrick Spiegel (March 17, 1911  – July 17, 1991) was an American psychiatrist, and expert on violence and combat stress and the 103rd President of the American Psychiatric Association.

Combat stress reaction: Combat stress reaction (CSR) is a term used within the military to describe acute behavioral disorganization seen by medical personnel as a direct result of the trauma of war.  Also known as "combat fatigue" or "battle neurosis", it has some overlap with the diagnosis of acute stress reaction used in civilian psychiatry.  It is historically linked to shell shock and can sometimes precurse post-traumatic stress disorder.

Acute stress reaction: Acute stress reaction (also called acute stress disorder, psychological shock, mental shock, or simply shock) is a psychological condition arising in response to a terrifying or traumatic event, or witnessing a traumatic event that induces a strong emotional response within the individual.  It should not be confused with the unrelated circulatory condition of shock/hypoperfusion.  Acute stress reaction (ASR) may develop into delayed stress reaction (better known as PTSD) if stress is not correctly managed.  ASR is characterized by re-living and avoiding reminders of an aversive event, as well as generalized hypervigilance after initial exposure to a traumatic event.  ASD is differentiated from PTSD as a disorder that precedes it, and if symptoms last for more than one month, it will develop into PTSD.  It can thus be thought of as the acute phase of PTSD.

George S. Patton slapping incidents: In early August 1943, Lieutenant General George S. Patton slapped two United States Army soldiers under his command during the Sicily Campaign of World War II.  Patton's hard-driving personality and lack of belief in the medical condition combat stress reaction, then known as "battle fatigue" or "shell shock", led to the soldiers becoming the subject of his ire in incidents on 3 and 10 August, when Patton struck and berated them after discovering they were patients at evacuation hospitals away from the front lines without apparent physical injuries.

Combat Stress Intervention Program: The Combat Stress Intervention Program (CSIP) is a 3-year United States Department of Defense-funded research program to study mental health issues experienced by veterans returning from Operation Iraqi Freedom and Operation Enduring Freedom.  The $1.5 million study, which is managed under the Military Operational Medicine Research Program, focuses on Combat Stress Disorder, Posttraumatic stress disorder, and other post-deployment transitional challenges.  The study also focuses on developing resources and solutions for such veterans.

Combat Stress (charitable organisation): Combat Stress is a registered charity in the United Kingdom offering residential and community treatment to former members of the British Armed Forces suffering from a range of mental health conditions including Post Traumatic Stress Disorder (PTSD).  Combat Stress provides treatment for all Veterans suffering with mental illness free of charge.  On average it takes 13 years for a Veteran to come to Combat Stress for treatment, however for those who served in Iraq and Afghanistan the time period is much lower.

Combat Support Hospital: A combat support hospital (CSH, pronounced "cash") is a type of modern United States military field hospital.  The CSH is transportable by aircraft and trucks and is normally delivered to the Corps Support Area in standard military-owned Demountable Containers (MILVAN) cargo containers.  Once transported, it is assembled by the staff into a tent hospital to treat patients.  Depending upon the operational environment (e.g., battlefield), a CSH might also treat civilians and wounded enemy soldiers.  The CSH is the successor to the Mobile Army Surgical Hospital.

Remote location stress reaction: Remote location stress reaction, in the past commonly known as logging fatigue, is a range of behaviours resulting from the stress of data logging which decrease the operator's working efficiency.

Critical incident stress management: Critical incident stress management (CISM) is an adaptive, short-term psychological helping-process that focuses solely on an immediate and identifiable problem.  It can include pre-incident preparedness to acute crisis management to post-crisis follow-up.  Its purpose is to enable people to return to their daily routine more quickly and with less likelihood of experiencing post-traumatic stress disorder (PTSD).  Evidence-based reviews, however, have concluded that CISM is ineffective for primary trauma victims, and should only be used for secondary victims, such as responding emergency services personnel.  CISM was never intended to treat primary victims of trauma.
