As States sent Union regiments south, on April 19, Baltimore mobs in control of the rail links attacked Union troops who were changing trains. Local leaders' groups later burned critical rail bridges to the capital and the Army responded by arresting local Maryland officials. Lincoln suspended the writ of habeas corpus where needed for the security of troops trying to reach Washington. John Merryman, one Maryland official hindering the U.S. troop movements, petitioned Supreme Court Chief Justice Roger B. Taney to issue a writ of habeas corpus. In June Taney, ruling only for the lower circuit court in ex parte Merryman, issued the writ which he felt could only be suspended by Congress. Lincoln persisted with the policy of suspension in select areas.
On 19 April 1906, Pierre Curie was killed in a road accident. Walking across the Rue Dauphine in heavy rain, he was struck by a horse-drawn vehicle and fell under its wheels, causing his skull to fracture. Curie was devastated by her husband's death.
On 19 April 1915, Jevdet Bey demanded that the city of Van immediately furnish him 4,000 soldiers under the pretext of conscription. However, it was clear to the Armenian population that his goal was to massacre the able-bodied men of Van so that there would be no defenders. Jevdet Bey had already used his official writ in nearby villages, ostensibly to search for arms, but in fact to initiate wholesale massacres. The Armenians offered five hundred soldiers and exemption money for the rest in order to buy time, but Jevdet Bey accused the Armenians of "rebellion" and asserted his determination to "crush" it at any cost. "If the rebels fire a single shot", he declared, "I shall kill every Christian man, woman, and" (pointing to his knee) "every child, up to here".
In 1944, with the Japanese position in the Pacific deteriorating rapidly, the IJA mobilized over 500,000 men and launched Operation Ichi-Go, their largest offensive of World War II, to attack the American airbases in China and link up the railway between Manchuria and Vietnam. This brought major cities in Hunan, Henan and Guangxi under Japanese occupation.
The final air attack mission (code-named Mad Dog Flight) comprised five B-26s, four of which were manned by American CIA contract aircrews and volunteer pilots from the Alabama Air Guard. One FAR Sea Fury (piloted by Douglas Rudd) and two FAR T-33s (piloted by Rafael del Pino and Alvaro Prendes) shot down two of these B-26s, killing four American airmen. Combat air patrols were flown by Douglas A4D-2N Skyhawk jets of VA-34 squadron operating from USS Essex, with nationality and other markings removed. Sorties were flown to reassure Brigade soldiers and pilots, and to intimidate Cuban government forces without directly engaging in acts of war.
By April 19, 1961, the Cuban government had captured or killed the invading exiles, and Kennedy was forced to negotiate for the release of the 1,189 survivors. Twenty months later, Cuba released the captured exiles in exchange for $53 million worth of food and medicine.
Late on 19 April, destroyers USS Eaton (code-named Santiago) and USS Murray (code-named Tampico) moved into Cochinos Bay to evacuate retreating Brigade soldiers from beaches, before fire from Cuban army tanks caused Commodore Crutchfield to order a withdrawal.
It is alleged that Escobar backed the 1985 storming of the Colombian Supreme Court by left-wing guerrillas from the 19th of April Movement, also known as M-19. The siege, a retaliation motivated by the Supreme Court studying the constitutionality of Colombia's extradition treaty with the U.S., resulted in the murders of half the judges on the court. M-19 was paid to break into the Palace and burn all papers and files on Los Extraditables, a group of cocaine smugglers who were under threat of being extradited to the U.S. by the Colombian government. Escobar was listed as a part of Los Extraditables. Hostages were also taken for negotiation of their release, thus helping to prevent the extradition of Los Extraditables to the U.S. for their crimes.

Antonio Diaz, a 52-year-old man walking in the park near 105th Street, was knocked to the ground by teenagers about 9:15 p.m., who stole his bag of food and bottle of beer. He was left unconscious but soon found by a policeman.

At 9 p.m. on April 19, 1989, a group of an estimated 30 – 32 teenagers who lived in East Harlem entered Manhattan's Central Park at an entrance in Harlem, near Central Park North. Some of the group committed several attacks, assaults, and robberies against persons walking, biking, or jogging in the northernmost part of the park and near the reservoir, and victims began to report the incidents to police. Within the North Woods, between 105th and 102nd streets, they were reported as attacking several bicyclists, hurling rocks at a cab, and attacking a pedestrian, whom they robbed of his food and beer, and left unconscious. The teenagers roamed south along the park's East Drive and the 97th Street transverse, between 9 and 10 p.m.
At least some of the group traveled further south to the area around the reservoir, where four men jogging were attacked by several youths. Among the victims was John Loughlin, a 40-year-old schoolteacher, who was severely beaten and robbed between 9:40 and 9:50. He was hit in the head with a pipe and stick, knocking him briefly unconscious. At a pre-trial hearing in October 1989, a police officer testified that when Loughlin was found, he was bleeding so badly that he "looked like he was dunked in a bucket of blood".
During a Copa del Rey semi-final against Getafe on 18 April, he scored a goal remarkably similar to Maradona's goal in the quarter-finals of the 1986 FIFA World Cup, known as the Goal of the Century. Messi collected the ball on the right side near the halfway line, ran 60 metres (66 yd), and beat five defenders before scoring with an angled finish, just as Maradona had done.
On 19 April 2011, Castro resigned from the Communist Party central committee, thus stepping down as party leader. Raúl was selected as his successor. Now without any official role in the country's government, he took on the role of an elder statesman.
