The ice did not break, and the hussars and infantrymen were able to board the Dutch ships. The French captured the Dutch admiral and the vessels' crews; neither side suffered any casualties. With the capture of 14 warships, 850 guns, and several merchant ships, the French conquest of the Netherlands was brought to an end. It is one of the few times in recorded military history wherein cavalry captured a fleet; José Antonio Páez's cavalry attack across the Apure River in 1818 is another example. The ships of the line, frigates, and corvettes received French crews in February 1795. France returned all her prizes to the Batavian Republic in May 1795 under the Treaty of The Hague; one of its other provisions was an indemnity of ƒ100 million.

The incident occurred during the Anglo-Russian invasion of Holland. It took place in a tidal trench in the channel between Texel and the mainland that was known as "De Vlieter", near Wieringen. Two of the vessels that were handed to the British were "Admiral de Ruyter" and "Gelderland". The traditional narrative of French cavalry storming and capturing the ships at Den Helder is primarily based on French sources. Dutch historian Johannes Cornelis de Jonge states that the Dutch fleet had already received orders on 21 January to offer no resistance. Instead, de Jonge states that a few French hussars merely crossed the ice to negotiate a handover by the Dutch officers. Captain Hermanus Reintjes, the Dutch commanding officer, stayed aboard the "Admiraal Piet Heyn" to await the arrival of general De Winter, who was scheduled to arrive in three days. De Winter subsequently had the officers and crews of the ships pledge an oath that they would peacefully surrender — similar to the oath administered at the surrender of the fleet at Hellevoetsluis several days earlier. De Jonge states that the misconception stems from an 1819 publication by Swiss general Antoine-Henri Jomini, whose account was subsequently cited by French historians.
