This match between Louis Paulsen and Adolf Schwarz was quickly played, often at the rate of two games per day, over July 21-24, 1879. The match took place immediately following the end of the 1st DSB Congress⁽ｹ⁾ in Leipzig, and can be considered part of the Congress.
Paulsen emerged the winner of the match with a score of 5/7 (+5 -2 =0).
Unfortunately, the German chess periodicals from this period are missing from <jnpope>'s site Chess Archeology⁽ｲ⁾. Since there was very little press coverage of even the main tournament outside of Germany, let alone this side match, detailed information is difficult to obtain. Luckily, Nordisk Skaktidende (1879)⁽ｳ⁻⁴⁾ provided some coverage of the match. The following is drawn from this source.
Leipzig GER, 1879.07.21 - 1879.07.24

After the recent death of Adolf Anderssen earlier in the year, Paulsen was widely regarded as the best player in Germany. However, Paulsen finished second in the main tournament, after Berthold Englisch. After the completion of the main tournament, Paulsen issued a d馭i to Englisch for a match. Previous obligations prevented Englisch from accepting, and he immediately returned to Vienna upon completion of the main tournament.
It was then arranged that Paulsen would play a seven game match with Schwarz, the third place finisher. Apparently the number of games were fixed, as Paulsen, after losing the first game, immediately won the next four, yet play continued, with each player winning one game apiece of the final two. No draws were scored during the entire match.
The Nordisk Skaktidende coverage seems to suggest that Paulsen won 100 M, and Schwarz 50 M for their play, suggesting the DSB⁽⁵⁾ sponsored the match as part of the Leipzig Congress.
