Pevensey (Eagle)

The rape of Pevensey lies between the rapes of Lewes and Hastings, from the coast at Seaford, Eastbourne and Pevensey north through Ashdown Forest to East Grinstead and the Surrey and Kent borders.

Its castle stands inside the walls of the Roman fort of Anderida above the Pevensey Levels. The honour is called the honour of the Eagle after its Norman lords of L'Aigle. A thirteenth-century jury said the barony owed 62 knights' fees to the castle-guard of Pevensey. Inside the rape, the archbishop of Canterbury holds the great liberty of South Malling (Church map).

Who he is

Name
Gilbert de l'Aigle (Gilbert de Aquila)
Title
Lord of the rape of Pevensey (the honour of the Eagle) and of L'Aigle in Normandy
Since
The mid-1180s, after his half-brother Richer disappears from the scutage records
Born
Not pinned
Family
Son of Richer de l'Aigle (died 1176) and Odelina. Wife: Isabel de Warenne, a rich widow (of Robert de Lacy, who died in 1193) and niece of William of Salisbury; the marriage date is not pinned. No surviving children: on his death in 1231 his English lands revert to the crown.
Confidence
medium

His father Richer lost and recovered the Sussex lands twice (Stephen took them; he sided with the Young King and had them restored in 1174). Gilbert found favour with John at his accession in 1199. Later he left court without leave to defend his Norman lands and John seized his English property (the date is not pinned; it belongs with the loss of Normandy, about 1203-04). William de Warenne offered a great fine for the lands and Gilbert had them back about 1215; he sided with the rebels and Louis in 1216, kept his lands after 1217, founded Michelham priory in 1229 and died in 1231.

Royal spending on Pevensey castle under Richard I (Wikipedia, from the Pipe Rolls) shows the crown also paid for the castle's works; who kept the castle itself on 1 January 1200 is not pinned.

Overlord

King John (for L'Aigle, as duke of Normandy)

What it holds

  • Pevensey castle within the Roman walls, and the borough of Pevensey (a limb of Hastings in the Cinque Ports)
  • The rape of Pevensey with its knights' fees and castle-guard
  • Ashdown chase in the north of the rape
  • The borough and hundred of East Grinstead
  • In Normandy: L'Aigle (France map)

How it was acquired

Henry I's grant to Gilbert de l'Aigle after the forfeiture of William, count of Mortain (1106); lost under Stephen, restored under Henry II.

Allies and rivals

The archbishop's men of South Malling; the Warenne earls at Lewes; the count of Eu at Hastings.

How things stand that morning

Gilbert de l'Aigle holds the honour and stands in John's favour. The custody of the castle itself is not pinned.

Wealth

The Pevensey Levels (grazing and salt), the downs at Eastbourne, the Wealden forest of Ashdown. No figures.

Military

Pevensey castle; the 62 fees of castle-guard reported by a thirteenth-century jury.

Threats

  • A cross-Channel lord with his chief lands in Normandy: if he must choose, he risks his English lands (as happens about 1203-04)

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

Places of note

  • Pevensey castle: Castle in the Roman fort

Where the sources disagree

Evidence: The family's history is set out on Wikipedia (L'Aigle family) from the scholarly literature; the castle's custody in January 1200 is not pinned.

On the map: The rape boundary is approximate; the archbishop's liberty of South Malling is drawn by the Church map.

The Chronica stops in 1199, so for 1200 the witness is the briefer Gesta Regum, which notes John's peace with Philip, the coronation of Isabella at Westminster on 8 October 1200, and matters touching Canterbury: the archbishop Hubert Walter as chancellor, the cathedral priory's quarrel with him, and the Lambeth college dispute lately settled by the pope.

  • Flowers of History, Roger of Wendover (about 1220 to 1235 at St Albans).
