In the Lydia's battle with the Natividad, the main topgallant staysail (top sail, middle mast) on the Lydia vanishes early in the battle. We can tell because the sail in front of it on the foremast is shot down. Later in the battle, the Natividad fires at the rigging, and then the main topgallant staysail is shot down. Also in the later shot, the top sail on the foremast briefly reappears. Then still later, both sails reappear for a shot of the Lydia sailing, and then they disappear again as the Lydia closes in to destroy the Natividad.

During the battle between the Lydia and the Natividad, on the Natividad, the railing between the upper and lower deck, where Alvarado is standing, loses and regains a drapery of ropes as the battle continues.

When the 'Lydia' arrives at the fortress of 'El Supremo,' Hornblower is told the ship is 'cleared for action' yet none of the guns on the quarterdeck are manned.

Several times sails shown already furled away in the wide shots, are still shown unfurled in the closeups.

The date on the first captain's log entry is a date in September that is only correct for the year 1808. During action in October, Hornblower says the Lydia has been at sea for eight months, which would mean it departed England in February 1808. However, the introduction of the film states that the voyage began in 1807.

Just before the Lydia sights land, Hornblower orders Lt Gerard to have the ship cleared for action. Hornblower then settles down to eat lunch in his cabin.

Aboard a frigate, the captain's cabin would not be usable to eat when either 'cleared for action' or being cleared for action. Part of the ships battery was contained in the captains cabin and the gun crews would be in the cabin removing bulkheads and preparing the guns for battle. Also all furniture was "struck below" (moved below deck) to provide room for the gun crews and minimize possible splinter injuries.

Set in 1807, the Lieutenants on Hornblower's ship all display the single shoulder epaulet - a rank insignia for Lieutenants which was not adopted by the Royal Navy until after 1812.

Hornblower promises Lady Barbara "that she will be home in time for the 'first robin.'" He would have known that English robins, unlike American ones, are not migratory, and remain in gardens throughout the winter.

It's 1807, and when Hornblower invites his officers for dinner before they go to capture the Natividad, they toast the King while sitting down, rather than standing to do so. This privilege was only given to the Royal Navy after 1830 when William IV became King, known as "the Sailor King." He had been a Royal Navy officer for many years himself, and knew how cramped things were on a ship, making standing for a toast difficult (The book makes a point of mentioning the fact that this practice was not allowed).

Throughout the battle with the Natividad, there is no significant change in the trim or setting of the sails on either ship, despite each making numerous changes in direction. The yards, and so the sails, should have been adjusted with each change of direction. Further, at times it can be seen that the sails of the ships are actually aback (being push backwards against a mast), a highly undesirable situation which would bring the ship to a stop. In at least one scene, this happens while the sails of the other ship, which is on a similar course, are well filled with wind.

In the closing scene, Captain Hornblower orders the sails down in the harbor and the ship begins to move yet there is clearly no wind.

The ship is moved away from the dock by the ebb-stream.

At the very end as the ship leaves the harbor for England, Hornblower orders the sails up (unfurled). A ship would be pulled out by rowing boats until away from the harbor else it would be thrashed in to the side of the dock by any wind strong enough to move it.

Sailships used to be launched by first letting the current (usually the ebb stream, though sometimes a strong river might provide enough current to do it independent of the tides) take her out into the open, then the sails would be set and trimmed to turn her around wind vane like until the sails can provide propulsion.

While free after escaping, the men see uniformed men in a rowboat and state that they are Dutch. One of the characters states that the Dutch are allied with France. Holland at the time was not as much an ally as a subject nation of France. During the time set in this film, Napoleon's brother Louis was the head of state of Holland.

As the Lydia delivers an 11-gun salute to Don Julian as he boards her, none of the guns recoil as they are fired.

They do not recoil because they are loaded only with powder, not shot. It would generally be a bad idea to shoot up the local harbor when firing a salute.

When Hornblower's ship, the Sutherland, is firing to "dismast" the French ships, the resulting damage is shown using closeups of the French decks. In one, a huge portion of a mast falls onto the deck. But it bounces lightly, and shows that it has a smooth bottom, revealing that it is a prop.

When Hornblower first meets El Supremo, they are interrupted by a man bringing word of the Natividad being sighted. El Supremo translates this for Hornblower though Hornblower is fluent in Spanish (having been a prisoner in Spain while an acting Lieutenant) and would have understood the message himself. This translation was most likely done for the benefit of the audience.

During the battle between the Lydia and the Natividad, the model of the Natividad is clearly held down by visible ropes.

When beating to quarters before engaging el Supremo's ship, one of the British sailors leans into a cannon. As he does so, the gun clearly moves, revealing it is a lightweight prop.

When Polwheal is running out of the Captain's cabin as they're going into battle with the Natividad, he bumps into a cannon and it moves slightly, indicating clearly that it's a wooden mock up, not several thousand pounds of iron, steel, or bronze. The same thing happens several times later in the film.

Once aboard the 'Witch of Endor,' Captain Hornblower calls on the the captured Royal Navy men being used as slave labor to take the vessel by force. During the ensuring fight, one man draws back his fist to punch a French soldier and his elbow can clearly be seen striking the man behind in the nose. The injured man then spends the remainder of the scene holding his nose and checking it for bleeding.

When the Spanish captain is yelling "fuego, fuego!" to fire the cannons, this is an erroneous translation from English to Spanish. "Fuego" in Spanish does mean "fire," but it is not a verb having anything to do with a weapon. Someone who yells "fuego!" would be alerting you to something which is burning. The correct command for firing a gun or cannon would be the verb "disparar," which means "to shoot." Thus, the correct command in Spanish to "fire the cannons" would be "dispara los cañones!" Or, for just "shoot!" [fire!] = ¡Dispara!.

Hornblower says that this was the first time he had to engage in a sword fight since "midshipman school." This is inaccurate. By this time in the book series, he had been engaged in many such fights over a period of years. Besides, midshipman are given daily lessons on board. There is no school.

The uniforms in this film bear only a passing resemblance to the uniforms of the day and in some cases no resemblance at all. For an accurate depiction of the uniforms, see the Hornblower series of TV movies, beginning with Horatio Hornblower: The Duel (1998).

Hornblower asks whether Lady Barbara is related to the Duke of Wellington. This is in 1807. Sir Arthur Wellesley was elevated to the Peerage after the Battle of Talavera in 1809 and to a Dukedom in 1814 after the Army invaded France. In 1807, he was still Sir Arthur. The title of Duke of Wellington did not exist.

At one point Hornblower and his officers give the loyal toast whilst seated. While it is true that the Royal Navy do toast the King or Queen seated, this tradition only dates to the reign of William IV (1830-1837), aka the Sailor King. At the date when this film is set, RN officers would still have got to their feet to toast the King.

The lookout posted near Alvarado's fortress uses a flashing signal device. This was not the practice of the Royal Navy until 1867. Source: Wikipedia - Signal Lamps.

When Lady Barbara falls in love with Hornblower during their return to England, she wears a fairly low-cut dress at least twice, and again in the movie's final scene--instead of the modest lace usually seen in her bodice. During the scene below decks before reaching England, she comes within a fraction of an inch of revealing too much. This likely pleased Virginia Mayo's fans in 1951, but was hardly the daring fashion statement made by a British lady in 1807.

During the battle between the Lydia and Natividad, a disturbance may be observed at Lydia's stern -strongly suggesting that the model used may have had a propeller.

During the opening narration, a world map is shown with "Ethiopia" in the middle of Africa (approx, where modern Zaire is located). In fact, Ethiopia occupies most of the "Horn of Africa," a peninsula on the east coast close -- it is across the Red Sea from the Arabian peninsula in Asia and several hundred miles from the position shown. No Royal Navy map would make such an error.

When the Witch of Endor escapes from Nantes the shot shows only a clear horizon ahead of her. However, Nantes is on the Loire River, about 37 miles upstream from the ocean. Since the river is only several hundred feet wide at Nantes, land should be visible in every direction.
