in 1865Battle of Five Forks – In Siege of Petersburg, Confederate General Robert E. Lee begins his final offensive.
The Battle of Five Forks was fought on April 1, 1865, southwest of Petersburg, Virginia, around Five Forks, Dinwiddie County, Virginia, during the Appomattox Campaign of the American Civil War. The battle, sometimes referred to as the "Waterloo of the Confederacy," pitted Union Maj. Gen. Philip H. Sheridan against Confederate Maj. Gen. George E. Pickett of Robert E. Lee's Army of Northern Virginia. Pickett's loss at Five Forks triggered Lee's decision to abandon his entrenchments around Petersburg and begin the retreat that led to his surrender at Appomattox Court House on April 9.

in 1946Formation of the Malayan Union.
The Malayan Union was a federation of the Malay states and the Straits Settlements of Penang and Malacca. It was the successor to British Malaya and was conceived to unify the Malay Peninsula under a single government so as to simplify administration. The Malayan Union later became the independent Federation of Malaya in 1948. The Federation of Malaya became the Federation of Malaysia in 1963, following the admission of Singapore, Sabah (North Borneo) and Sarawak to the new federation. Singapore left the federation and became independent in 1965.
Marie-Sophie Germain was a French mathematician, physicist and philosopher. Despite initial opposition from her parents and difficulties presented by a gender-biased society, she gained education from books in her father's library and from correspondence with famous mathematicians such as LaGrange, Legendre, and Gauss. One of the pioneers of elasticity theory, she won the grand prize from the Paris Academy of Sciences for her essay on the subject.

Johann Joseph Abert was a German composer. An ethnic German from the Sudetenland, he is also known by his Czech name Jan Josef Abert.
Lev Davidovich Landau was a prominent Soviet physicist who made fundamental contributions to many areas of theoretical physics. His accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions, the Ginzburg–Landau theory of superconductivity, the theory of Fermi liquid, the explanation of Landau damping in plasma physics, the Landau pole in quantum electrodynamics, and the two-component theory of neutrinos. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98 °C).
