Question: Was Halma or Battle Sheep introduced first?

full_context: Document 1: Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus. Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain. One player must win; there are no draws. The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem. It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash. The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production. Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Document 2: Bear games: Bear games is a category of board games of which many have historical roots in the Roman Empire. They were played in parts of the Empire as far away as Turkey and France and are still played today, especially in Italy. All of the games are two-player abstract strategy board games. Normally, the game is played with three hunters and one bear on a patterned board. It bears similarity to the hunt games such as the Fox games, Rimau-rimau, and Bagha-Chall, however, there are no captures involved. The three hunters are trying to hem in the bear, and block its movements.
Document 3: Halma: Halma (from the Greek word ἅλμα meaning "jump") is a strategy board game invented in 1883 or 1884 by George Howard Monks, a US thoracic surgeon at Harvard Medical School. His inspiration was the English game "Hoppity" which was devised in 1854.
Document 4: Kotu Ellima: Kotu Ellima is a two-player abstract strategy board game from Sri Lanka and India. The game is similar to draughts and Alquerque as players hop over one another's pieces to capture them. However, unlike draughts and standard Alquerque, the game is played on an expanded Alquerque board consisting of four triangular boards attached to the four sides of an Alquerque board. Also, pieces can move and capture in any direction from the beginning. There is no promotion to King. Its actual closest relatives are Peralikatuma and Sixteen Soldiers which are also from the Indian subcontinent. The only real difference between these three closely related games is the number of pieces. In Sixteen Soldiers, each player has 16 pieces hence the name of the game. In Peralikatuma, each player has 23 pieces. In Kotu Ellima, each player has 24 pieces. The whole board is covered with pieces except the middle point reminiscent of Alquerque. Kotu Ellima is also related to the Indonesian game of Permainan-Tabal.
Document 5: Squatter (game): Squatter is a board game that was launched at the Royal Melbourne Show in 1962, invented by Robert Crofton Lloyd. With more than 500,000 games sold in Australia alone, it became the most successful board game ever developed in Australia. Superficially, Squatter has the appearance of a "Monopoly"-type game. However, unlike Monopoly, all players remain in the game until the end. Players each start the game with their own sheep station and aim to be the first player to improve and irrigate their pastures and then fully stock their sheep station. Players run their sheep station as a business venture, to earn enough money to pay for the seasonal running expenses and to finance the improvements that are required to win the game. The Squatter game presents players with a mixture of strategy and luck that reflects the many challenges facing any form of livestock raising. These challenges include droughts, floods and bushfires, as well as disease, variable livestock prices, and luck. In 1999, a version became available on PC CD-ROM. However the PC version was not commercially successful and is no longer available.
Document 6: Kharbaga: Kharbaga is a two-player abstract strategy game from Africa. In a way, it is a miniature version of Zamma; however, there are more diagonal lines per square on the board as compared to Zamma. The game is considered part of the Zamma family. The game is also similar to Alquerque and draughts. The board is essentially an Alquerque board with twice the number of diagonal lines or segments allowing for greater freedom of movement. The initial setup is also similar to Alquerque, where every space on the board is filled with each player's pieces except for the middle point of the board. Moreover, each player's pieces are also set up on each player's half of the board. The game specifically resembles draughts in that pieces must move in the forward directions until they are crowned "Mullah" (or "Sultan") which is the equivalent of the King in draughts. The Mullah can move in any direction.

Document 9: Sher-bakar: Sher-bakar is a two-player abstract strategy board game from Punjab, India. It is a hunt game. It uses an Alquerque board, and therefore, Sher-bakar is specifically a tiger hunt game (or tiger game). There are two tigers attempting to elude and capture as many of the other player's pieces which in other hunt games in this part of the world is often referred to as a goat, cows, lamb, or men. An interesting and uncommon feature in this game is that the goats, cows, lamb, or men are piled up on four points of the board at the beginning of the game. Piling up pieces is an unusual feature in hunt games or any board game in general. The only other hunt game that uses this feature is Bagh bandi, a game closely related to Sher-bakar. Hereinforth, the white pieces will be referred to as goats.
