A "significant proportion" headed via a tunnel to the terraces behind the goal, entering "relatively full' central pens that were fenced on all sides. There was then a severe crush.
Ninety-six men, women and children died as a result of the crush. All except one were Liverpool supporters.
The youngest victim was 10-year-old Jon-Paul Gilhooley. The oldest was Gerard Baron, who was 67. Thirty-eight of the victims were aged 19 or under.

Why are the new inquests being held?
At the original inquests, the then South Yorkshire coroner Dr Stefan Popper decided the hearing should only investigate events before a cut-off time of 3.15pm. He argued that it was unnecessary to look at events beyond this time.
On the evidence of pathologists, he said all those who died would have suffered irreversible brain damage by that time and were beyond saving.
That meant the hearing would not look into the emergency response to the disaster. This was a highly controversial decision strongly disputed by the families of the deceased.
In 2009, the government set up the Hillsborough Independent Panel to review documents relating to the disaster. In September 2012, the panel produced a report based on 450,000 pages of documents previously stored by the government, other public bodies, private companies and individuals.
A month later, the Attorney General applied for the original inquests to be quashed. In December 2012, following a campaign by the bereaved families, the High Court ordered a fresh hearing.
What has been heard so far?
The inquests began on 31 March 2014 at a purpose-built courtroom in Warrington, Cheshire.
The jury of six men and three women began by listening to profiles of all those who died, read by - or on behalf of - their families.
They went on to hear evidence about the design of the stadium, police planning and preparation, the emergency response as well as detailed medical evidence and the movements of the 96 fans who died.
The inquests heard claims from at least one medical expert that a number of victims might have been saved by a "sustained and earlier" intervention.
Who has been involved in the hearings?
More than 500 witnesses have been called and 4,000 pages of documents and hours of video evidence shown.
The 1989 match commander David Duckenfield and South Yorkshire Police are among the 12 individuals and 12 organisations listed as interested parties along with 95 of the 96 victims.
No living relatives could be traced for one of the victims, Martin Wild.
What will the jury have to consider?
There are 14 questions the Hillsborough jury need to answer including whether the 96 victims of the disaster were unlawfully killed and whether opportunities were lost to save lives on the day of the disaster, 15 April 1989.
To consider whether fans were unlawfully killed, the jury would have to be sure match commander David Duckenfield was responsible for their manslaughter, the coroner Sir John Goldring said.
To answer yes to that question, the jury must agree with four points:
Firstly, that Ch Supt David Duckenfield owed a duty of care to the 96 who died
Secondly, that he was in breach of that duty of care
