Fought September 30, 1745, between 18,000 Prussians, under Frederick the Great, and 35,000 Austrians, under Prince Charles of Lorraine. The Prussians attacked the Austrian position and the Austrians, failing to display their usual courage made no stand against the steady advance of the Prussian infantry, and were driven back in confusion, with a loss of 6,000 killed, wounded and prisoners, and 22 guns. The Prussians lost between three and four thousand men.

Soissons.

Fought 486, and notable as the first military exploit of Clovis, the founder of the Merovingian dynasty, who here defeated Syagrius, Count of Soissons, and annexed his dominions.

Solebay (Dutch Wars).

Fought May 28, 1672, when the French and English fleets, together about 140 sail, under the Comte d'Estrées and the Duke of York, were surprised at anchor, by a Dutch fleet of 115 ships, under de Ruyter. The French were first attacked, but soon edged out of the fight, and the bulk of the work fell to the English. The battle was indecisive, for though the Dutch lost five or more ships, and the English one only, the allied fleet was too crippled to take the offensive for over a month after the action.

Solferino (Franco-Austrian War).

Fought June 24, 1859, between 150,000 Austrians, under the Emperor Francis Joseph, with Generals Wimpffen and Scholick in actual command, and the French and Piedmontese, under Napoleon III and Victor Emmanuel. The French attacked the Austrian position on the heights round Solferino, which were held by Scholick, and after very hard fighting, they were captured by the corps of Macmahon and Baraguay d'Hilliers. Meanwhile Wimpffen, with three Army Corps, attacked the French left, but was held at bay throughout the day by Marshal Niel's corps, and when night fell, the Austrian centre being broken, Francis Joseph had no option but to retreat, and consequently recrossed the Mincio. The Austrians lost 22,000 killed, wounded and missing. The allies' losses were 18,000, of which number the Piedmontese corps of 25,000 lost 4,000.

Solway Moss (Scottish Wars).

Fought December 14, 1542, between the Scottish invading army, under Oliver Sinclair, and a band of 500 English borderers, under Thomas Dacre and John Musgrave. The Scots were totally defeated, and many important nobles captured.
