In the original version, which is hung at Malmaison, a very young-looking Bonaparte wears an orange cloak and rides a black and white piebald horse. The Charlottenburg shows Napoleon with a slight smile, wearing a red cloak and mounted on a chestnut horse. There are two versions hung at Versailles, the first shows a stern-looking Napoleon riding a dappled grey horse, while the second shows an older Napoleon, with shorter hair wearing an orangy-red cloak and mounted on a black and white horse. A final version, from the Belvedere, is almost identical to the first Versailles version. In all versions, the horse is rearing and Napoleon is pointing, guiding his men over difficult pass. Behind the horse and rider, there is a small view of soldiers struggling to get their cannons over the pass. The sky is stormy and dark.
In one account, David asks Napoleon to pose and he answers “Sit? For what good? Do you think that the great men of Antiquity for whom we have images sat?”
“But Citizen First Consul,” David responded, “I am painting you for your century, for the men who have seen you, who know you, they will want to find a resemblance.”
“A resemblance? It isn't the exactness of the features, a wart on the nose which gives the resemblance. It is the character that dictates what must be painted...Nobody knows if the portraits of the great men resemble them, it is enough that their genius lives there.”
After failing to persuade Napoleon to sit still, David copied the features of a bust of the First Consul. To get the posture correctly, David had his son perch on top a ladder.
Records indicate that Napoleon did not lead his men over the pass. Instead, General Maréscot led the army while Bonaparte followed after them by several days. By the time he crossed, the sky was sunny and the weather calm, although it remained cold and the ground covered with snow.
Dorsaz later related that the mule slipped during the ascent into the mountains. Napoleon would have fallen over a precipice had Dorsaz not been walking between the mule and the edge of the track. Although Napoleon showed no emotion at the time, he began questioning his guide about his life in the village of Bourg-Saint-Pierre. Dorsaz told Napoleon that his dream was to have a small farm, a field and cow. When the First Consul asked about the normal fee for alpine guides, Dorsaz told him that guides were usually paid three francs. Napoleon then ordered that Dorsaz be paid 60 Louis, or 1200 francs for his "zeal and devotion to his task" during the crossing of the Alps. Local legend says that Dorsaz used the money to buy his farm and marry Eléonore Genoud, the girl he loved.
